Transistors Without Semiconductors

CNMS User Newsletter
CNMS User Newsletter

Recent work published by Professor Yoke Khin Yap (Physics) on transistors without semiconductors has gained attention at the Center for Nanophase Materials Sciences (CNMS) at Oak Ridge National Laboratory (ORNL). Yap’s work “Room Temperature Tunneling Behaviors of Boron Nitride Nanotubes Functionalized with Gold Quantum Dots,” first appeared in CNMS Research Highlights, and then later in the September issue of the CNMS User Newsletter.

This work is now being highlighted by Dr. Sean Smith, Director of CNMS, during his overview talk in the Triennial Review of CNMS. The triennial review is being held on September 24-26, 2013 at CNMS as attended by the review team of the U.S. Department of Energy, the CNMS Advisory Committee Review Panel, and scientists in CNMS.

On September 25, Professor Yap presented an invited talk entitled “Transistors without semiconductors: tunneling behavior of functional boron nitride nanotubes” during the review. The highlights are related to a Yap article recently published in Volume 25, Issue 33/2013, pages 4544-4548 of Advanced Materials (http://onlinelibrary.wiley.com/doi/10.1002/adma.201301339/abstract).

Yap’s coauthors include Professor John Jaszczak, research scientist Dongyan Zhang, postdoctoral researchers Chee Huei Lee and Jiesheng Wang, and graduate students Madhusudan A. Savaikar, Boyi Hao and Douglas Banyai of Michigan Tech; Shengyong Qin, Kendal W. Clark and An-Ping Li of the Center for Nanophase Materials Sciences at ORNL; and Juan-Carlos Idrobo of the Materials Science and Technology Division of ORNL.


Debasis Datta Inducted into CSA Academy 2013

Dr. Debasis Datta was inducted into Michigan Technological University’s Academy of Sciences and Arts on September 13, 2013. Datta graduated with a PhD in Physics from Michigan Technological University in 1994. His research work at Tech resulted in ten publications in American Physical Review. Following the completion of his postdoctoral work, he started his career in Information Technology in 1996 as a software engineer in the IT services industry. During his 16 year IT career, Debasis worked at DaimlerChrysler, PeopleSoft, Oracle and General Motors Corporation where he is currently employed.

Yong Meng Sua FigureTitle: Intrinsic Correlations of Quantum Lights in Macroscopic Environments

Advisor: Dr. Kim Fook Lee

Co-Advisor: Dr. Jacek Borysow

Quantum Information Science (QIS) is an up-and-coming field that exploits the peculiar properties of quantum superposition and entanglement by using quantum objects, such as atoms, molecules, photons and phonons. As photons interact weakly with their environment and are very robust against environmental disturbance, they are considered the most promising candidates for the applications of QIS. The preservation of intrinsic quantum properties of light in macroscopic environments will be the key for practical realization of QIS. For my Ph.D. research, I’m working with different quantum light sources, spanning from single photon systems such as entangled photons to millions of photons such as weak coherent light. I study the intrinsic correlations of quantum light in macroscopic environments, while mainly concerned with their applications in quantum metrology and communications.

Quantum Dots on a Boron Nitride Nanotube

Since it was published online in Advanced Materials, the article “Room-Temperature Tunneling Behavior of Boron Nitride Nanotubes Functionalized with Gold Quantum Dots,” coauthored by physics professor Yoke Khin Yap, has received exceptional attention. The related new release, “Beyond Silicon: Transistors without Semiconductors,” appeared in numerous websites and blogs. The Altmetric system, which measures the social impact of a scholarly literature, gave it a score of 86.

The article has scored higher than all articles from Advanced Materials published within six weeks on either side of its publication date. Articles from this journal typically receive more attention than average, with a mean Altmetric score of 7.1 compared to the global average of 3.8. This article’s score places in the 99th percentile of the 1.4 million articles across all journals tracked by Altmetric.

Yap’s article also highlighted in a number of professional societies, including IEEE Spectrum of the Institute of Electrical and Electronics Engineers , Ceramic Tech Today from the American Ceramic Society, and the Center for Nanophase Materials Sciences in Oak Ridge National Laboratory.

The researchers’ work is described in the article “Room Temperature Tunneling Behavior of Boron Nitride Nanotubes Functionalized with Gold Quantum Dots,” and published in issue 33/2013, pages 4544-4548 of Advanced Materials.
