Quantum Manipulation of Valleys in Bilayer Graphene: Theory and Applications
G. Y. Wu, N. -Y. Lue, Y. -C. Chen
Quantum manipulation of valleys in bilayer graphene is investigated. We establish an effective Schrodinger model, and identify two key mechanisms for valley manipulation - band str…
The VOI-Based Valleytronics
G. Y. Wu, N. -Y. Lue, Y. -C. Chen
We discuss the valley-orbit interaction (VOI) and the concept of VOI based valleytronics. Potential of such valleytronics is illustrated, with graphene as an example material, in s…
Valley-based FETs in graphene
M. -K. Lee, N. -Y. Lue, Y. -C. Chen +2
An analogue of the Datta-Das spin FET is investigated, which is all-graphene and based on the valley degree of freedom of electrons / holes. The "valley FET" envisioned consists of…
Role of heating and current-induced forces in the stability of atomic wires
Z. Yang, M. Chshiev, M. Zwolak +2
We investigate the role of local heating and forces on ions in the stability of current-carrying aluminum wires. We find that heating increases with wire length due to a red shift…
Are current-induced forces conservative?
M. Di Ventra, Yu-Chang Chen, T. N. Todorov
The expression for the force on an ion in the presence of current can be derived from first principles without any assumption about its conservative character. However, energy func…
