Electronic gadgetry gets tinier and more powerful all the time, but at some point, the transistors and myriad other component parts will get so little they won’t work. That’s because when things get really small, the regular rules of Newtonian physics quit and the weird rules of quantum mechanics kick in. When that happens, as physics professor and chair Ravindra Pandey puts it, “everything goes haywire.”
Theorists in the field of molecular electronics hope to get around the problem by designing components out of a single molecule. Pandey’s group has done just that–theoretically–by modeling a single-molecule field-effect transistor on a computer.
“Transistor” has been an oft-used but rarely understood household word since cheap Japanese radios flooded the US market back in the 1960s. Field-effect transistors form the basis of all integrated circuits, which in turn are the foundation of all modern electronics.
A simple switch either diverts current or shuts it off. Transistors can also amplify the current by applying voltage to it (that’s how amplifiers work).
A diagram of Pandey’s three-terminal single-molecule transistor looks like an elaborate necklace and pendant, made up of six-sided rings of carbon atoms bedecked with hydrogen and nitrogen atoms. His group demonstrated that the electrical current running from the source to the drain (through the necklace) rises dramatically when voltage applied at the gate (through the pendant) reaches a certain level.
This happens when electrons in the current suddenly move from one orbital path around their atoms to another. Or, as Pandey says, “Molecular orbital energies appear to contribute to the enhancement of the source-drain current.”
Their virtual molecule may soon exist outside a computer. “Several experimental groups are working to make real our theoretical results,” says Pandey.
An article on the molecular transistor, “Electronic Conduction in a Model Three-Terminal Molecular Transistor,” was published in 2008 in the journal Nanotechnology, volume 19. Coauthors are physics graduate student Haiying He and Sashi Karna of the Army Research Lab.

The Graduate School needs your help in welcoming our new graduate students and helping them successfully begin their career at Michigan Tech. Faculty, staff and student volunteers are needed to facilitate discussion during orientation. This is your opportunity to help enhance graduate education at Michigan Tech.
The training will help graduate students and advisors set expectations for graduate education and introduce students to basic concepts in responsible conduct for research. The program centers around an interest based approach that has been developed by Michigan State for use in their graduate programs.
Volunteers will help facilitate discussion at a table with six or seven new graduate students. The discussion will center around two vignettes that depict typical graduate student and faculty interactions. Volunteers will participate in one of the training sessions offered on Monday, August 24th from 1:00 – 3:00pm and Tuesday, August 25th from 10am – noon.
Orientation begins at 9am on Wednesday, August 26th.
If you would like to volunteer, please register at:
http://www.gradschool2.mtu.edu/registration/events/
After registering, you will receive a confirmation e-mail with the locations for the training and orientation, along with reminders as we get closer to the event.
Please contact Debra Charlesworth with any questions about orientation.
This seminar along with handouts is now available online. Look in the Archives for the July 7, 2009 seminar. It will be online for approximately one year.
Join the Graduate School to learn the basics of Adobe Acrobat. Michigan Tech has a site license for this software, and all theses and dissertations are required to be submitted using this file format. We’ll talk about how to generate a pdf, how to edit a pdf file, how to embed fonts, and all about hyperlinks and bookmarks.
Please register for the event at our online registration site:
http://www.gradschool2.mtu.edu/registration/events/
Once you register, you will receive a confirmation with the location and a reminder of the date and time. Space is limited, so register early! The seminar will be taped and available online for those unable to join us at this time.
Michigan Tech looks forward to welcoming our new graduate students from summer and fall semester. All new degree seeking students will be invited to orientation on August 26th beginning at 9am in the Memorial Union Ballroom. Registration and light snacks will be available beginning at 8:30am. Lunch is included in the program, and will be followed by a round table session designed to introduce students to the services available on campus. Online registration is now closed. Students may register onsite, and will be accommodated as space permits.
In addition to the orientation session sponsored by the Graduate School, students may also be required to attend sessions sponsored by:
- their graduate program (contact programs for details)
- the Center for Teaching, Learning, and Faculty Development
- International Programs and Services
Questions about Graduate School orientation may be directed to Debra Charlesworth or Carol Wingerson.

The Sustainable Futures Institute (SFI) is sponsoring a poster session on Monday, June 22, in Memorial Union Ballroom 2 from 1 to 2:15 p.m. The event is open to the campus and local communities.
Both undergraduate and graduate students as well as faculty members from across the campus community will be displaying posters illustrating sustainability research and initiatives. These posters represent a broad range of sustainability action taking place at SFI and on the Michigan Tech campus.
Several posters in this year’s session will highlight the progress of ongoing research by the students involved in the Sustainable Futures Integrated Graduate Education and Research Traineeships program and its Wood-to-Wheels projects.
Since the poster session coincides with meetings of the SFI Advisory Board, members will be on hand. Attendees will have the chance to meet and mingle with board members, who represent the following: Caterpillar, Dow Corning, General Motors, The Great Lakes Commission, Kimberly-Clark, US Air Force, Steelcase, Motorola, Los Alamos National Laboratory of the Department of Energy, Nelson Mandela School of Public Policy and Urban Affairs at Southern University and A&M College, and the USDA Forest Service.
This poster session is intended to strengthen the network of scholars interested in promoting the important research, education and outreach work in sustainability on the Michigan Tech campus and in the community.

Michigan Tech’s College of Engineering graduates a higher percentage of women with PhDs in engineering than any other engineering school in the nation, the American Society for Engineering Education (ASEE) reports.
Forty percent of Michigan Tech’s engineering doctoral degrees were awarded to women, according to the ASEE’s annual report, “Engineering by the Numbers.” The report is based on data from 2008. The next highest percentage of women PhD recipients in engineering was 38.7 percent, at the University of Rochester.
“What great news,” said Jacqueline Huntoon, dean of the Graduate School. “I congratulate the faculty in our College of Engineering and the Graduate School staff on recruiting and retaining these outstanding women. Michigan Tech’s STEM (science, technology, engineering and math) focus makes it challenging for us to maintain high levels of gender diversity on our campus because STEM programs tend to attract males. We plan to build on this success and continue to increase the diversity of our students.”
According to the report, only engineering schools that award at least 25 doctoral degrees during the year are ranked. There were 100 engineering schools nationwide that awarded 25 or more PhDs during 2008.
In undergraduate engineering degrees, Michigan Tech ranked third in the nation in numbers of bachelor’s degrees in mechanical engineering; 11th in numbers of civil engineering bachelor’s degrees; 16th in both computer engineering and electrical engineering; and 22nd in the number of bachelor’s degrees awarded by the College of Engineering.
“At a time when the state, nation and world need more women in engineering, I am pleased that the percentage of women receiving engineering PhDs at Michigan Tech is the highest in the nation,” said Tim Schulz, dean of the College of Engineering. “As these young women rise to leadership positions in industry, government and academia, they will serve as excellent role models for future generations.”
