January 13, 2010
Author(s)
Vinod K. Tewary
This paper is an erratum that corrects some typographical errors in our earlier paper "Parametric interatomic potential for graphene" by V.K. Tewary and B. Yang, published in Physical Review B 79, 075442 (2009).

Molecular transistors scrutinized

December 23, 2009
Author(s)
James G. Kushmerick
Transistors have been made from single molecules, where the flow of electrons is controlled by modulating the energy of the molecular orbitals. Insight from such systems could aid the development of future electronic devices.
