Electronic states of graphene quantum dots induced by nanobubbles
We analyze the effects of the strain-induced pseudo-magnetic fields (PMFs) originating from nanobubbles (NBs) to examine the possibility for a graphene quantum dot (QD) created by strain engineering. We study ...

Influence of Coupling Strength Between a Magnetic Quantum Dot and Quantum Hall Edge Channels on Valley-isospin-dependent Dirac Fermion Transport
We investigate Dirac fermion transport through opposite quantum Hall edge channels in armchair graphene nanoribbons where a magnetic quantum dot (MQD) is placed between the edges. The resulting conductance sho...

Gate-tunable Thermoelectric Effects in a Graphene/WS2 van der Waals Heterostructure
Thermoelectric effects of Dirac fermions through a van der Waals (vdW) heterostructure consisting of graphene and tungsten diselenide (WS2) are theoretically investigated. When the lattice temperature of the top ...
