Pandey Group Models Molecular Transistor

Published in Tech Today

by Marcia Goodrich, senior writer

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.

Michigan Tech Tops in the Nation for Women Earning Engineering PhDs

From Tech Today

by Jennifer Donovan, public relations director

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.”
