Reversible Engineering of Topological Insulator Surface State Conductivity through Optical Excitation
Faji Xie, Zhen Lian, Shuai Zhang +13
Despite the broadband response, limited optical absorption at a particular wavelength hinders the development of optoelectronics based on Dirac fermions. Heterostructures of graphe…
Observation of superconducting phase transition in InN
Zhi-Yong Song, Liyan Shang, JunHao Chu +3
InN superconductivity is very special among III-V semiconductors, because other III-V semiconductor (like GaAs, GaN, InP, InAs etc.) usually lacks strong covalent bonding and seldo…
Phase transition and anomalous scaling in the quantum Hall transport of topological insulator Sn-Bi1.1Sb0.9Te2S devices
Faji Xie, Shuai Zhang, Qianqian Liu +12
The scaling physics of quantum Hall transport in optimized topological insulators with a plateau precision of ~1/1000 e2/h is considered. Two exponential scaling regimes are observ…
Non-neutral charged two-dimension system and its quasihole structure
Ting-Ting Kang
Most of our current knowledge on condensed matters contains a default assumption: the matters are neutral charged. On the other hand, the two-dimension(2D) vortex-Coulomb gas charg…
Screening in coupled low-dimensional systems: an effective polarizability picture
Ting-Ting Kang
The screening of an individual low-dimensional object can be strongly influenced by the objects nearby. We propose that such environment's influence can be absorbed into an effecti…
An artificial charge-density-wave conductor realized by double quantum wells
Ting-Ting Kang
Charge-density-wave (CDW) is a modulation of the conduction electron density in a conductor. Under low temperature, it can spontaneously happen in some compounds that consist of an…
