Half-Valley Ohmic Contact and Contact-Limited Valley-Contrasting Current Injection
Xukun Feng, Chit Siong Lau, Shi-Jun Liang +3
Two-dimensional (2D) ferrovalley semiconductor (FVSC) with spontaneous valley polarization offers an exciting material platform for probing Berry phase physics. How FVSC can be inc…
Intrinsic persistent spin helix in 2D T-XY (XY=P, As, Sb and Bi)
San-Dong Guo, Xu-Kun Feng, Dong Huang +2
The persistent spin helix (PSH) is robust against spin-independent scattering and renders an extremely long spin lifetime, which can improve the performance of potential spintronic…
Upper bound of a band complex
Si Li, Zeying Zhang, Xukun Feng +5
Band structure for a crystal generally consists of connected components in energy-momentum space, known as band complexes. Here, we explore a fundamental aspect regarding the maxim…
Emergent Anti-ferromagnetism in a Y -Shaped Kekulé Graphene
Chenyue Wen, Wanpeng Han, Xukun Feng +5
Antiferromagnetic (AF) transitions of birefringent Dirac fermions created by a Y-shaped Kekulé distortion in graphene are investigated by the mean-field theory and the determinant…
Two-dimensional Janus Si dichalcogenides: A first-principles study
San-Dong Guo, Xu-Kun Feng, Yu-Tong Zhu +2
Strong structural asymmetry is actively explored in two-dimensional (2D) materials, because it can give rise to many interesting physical properties. Motivated by the recent synthe…
