Valley-dependent resonant tunneling through double magnetic barriers in suspended graphene
Nojoon Myoung, Gukhyung Ihm
We theoretically investigate the effects of strain-induced pseudomagnetic fields on the transmission probability and the ballistic conductance for Dirac fermion transport in suspen…

Large Current Modulation and Spin-Dependent Tunneling of Vertical Graphene/MoS Heterostructures
Nojoon Myoung, Kyungchul Seo, Seung Joo Lee +1
Vertical graphene heterostructures have been introduced as an alternative architecture for electronic devices by using quantum tunneling. Here, we present that the current on/off r…

Magnetic Quantum Dot: A Magnetic Transmission Barrier and Resonator
H. -S. Sim, G. Ihm, N. Kim +1
We study the ballistic edge-channel transport in quantum wires with a magnetic quantum dot, which is formed by two different magnetic fields B^* and B_0 inside and outside the dot,…
