Seminar
Quantum transport simulation for ballistic graphene devices
Wednesday, 22 April 2015, 16:30-18:00
Talk given by Dr. Ming-Hao Liu
Institut für Theoretische Physik
Universität Regensburg
Recent progress on fabricating high quality graphene devices has strongly
enhanced the electron mean free path, making micron-scale ballistic transport in
graphene experimentally feasible. Quantum transport simulation based on the
real-space Green's function method that can fully take into account the graphene
sample and complex gating geometry therefore becomes a powerful tool in revealing
and identifying the interesting physics of Dirac electron waves in transport
experiments, such as Fabry-Perót interference (in suspended monolayer
graphene [1] and hBN-encapsulated bilayer graphene [2]), ballistic snake states [3],
and electron guiding [4]. In this talk, how to perform such realistic quantum
transport simulations will be introduced at an appropriate depth, and the physics
of these experiments [1-3] will be briefly discussed.
