Significant reduction in semiconductor interface resistance via interfacial atomic mixing
Qichen Song, Jiawei Zhou, Gang Chen
The contact resistance between two dissimilar semiconductors is determined by the carrier transmission through their interface. Despite the ubiquitous presence of interfaces, quant…
Evaluation of diffuse mismatch model for phonon scattering at disordered interfaces
Qichen Song, Gang Chen
Diffuse phonon scattering strongly affects the phonon transport through a disordered interface. The often-used diffuse mismatch model assumes that phonons lose memory of their orig…
Dirac-Electrons-Mediated Magnetic Proximity Effect in Topological Insulator / Magnetic Insulator Heterostructures
Mingda Li, Qichen Song, Weiwei Zhao +8
The possible realization of dissipationless chiral edge current in a topological insulator / magnetic insulator heterostructure is based on the condition that the magnetic proximit…
Three-dimensional non-Bosonic non-Fermionic quasiparticle through a quantized topological defect of crystal dislocation
Mingda Li, Qichen Song, Mildred S. Dresselhaus +1
It is a fundamental postulate that quasiparticles in 3D space obey either Bosonic or Fermionic statistics, satisfying either canonical commutation or anti-commutation relation. How…
