A new alloy for Al-chalcogen system: AlSe surface alloy on Al (111)
En-Ze Shao, Kai Liu, Hao Xie +6
Metal chalcogenide is a promising material for studying novel underlying physical phenomena and nanoelectronics applications. Here, we systematically investigate the crystal struct…
Exploring Native Atomic Defects in NiTe2
Wen-Xiao Wang, Kaihui Li, Xiaoshan Dong +9
Nickel ditelluride (NiTe2), a new discovered type-II Dirac semimetal whose Dirac node lies close to its Fermi level, is expected to exhibit exotic phenomena including Lifshitz tran…
Phase-dependent epitaxy for antimonene growth on silver substrate
Kai Liu, Keke Bai, Jing Wang +2
Antimonene is a novel two-dimensional topological semiconductor material with strain driven tunable electronic structure for future electronic and spintronic devices, but the growt…
Segregation growth and self-organization of ordered S atomic superlattices confined at interface between graphene and substrates
Dong-Lin Ma, Zhong-Qiu Fu, Ke-Ke Bai +7
Ordered atomic-scale superlattices on surface hold great interest both for basic science and for potential applications in advanced technology. However, controlled fabrication of s…
The tunnelling spectra of quasi-free-standing graphene monolayer
Si-Yu Li, Ke-Ke Bai, Wei-Jie Zuo +7
With considering the great success of scanning tunnelling microscopy (STM) studies of graphene in the past few years, it is quite surprising to notice that there is still a fundame…
Realization of room-temperature ferromagnetic semiconducting state in graphene monolayer
Yu Zhang, Xue-Lei Sui, Dong-Lin Ma +3
Room-temperature ferromagnetic semiconductor is vital in nonvolatile digital circuits and it can provide an idea system where we can make use of both charge and spin of electrons.…
Detecting giant electron-hole asymmetry in graphene monolayer generated by strain and charged-defect scattering via Landau level spectroscopy
Ke-Ke Bai, Yi-Cong Wei, Jia-Bin Qiao +5
The electron-hole symmetry in graphene monolayer, which is analogous to the inherent symmetric structure between electrons and positrons of the Universe, plays a crucial role in th…
Magnetic-field-assisted electron confinement and valley splitting in strained graphene
Jun-Fang Liu, Ke-Ke Bai, Jia-Bin Qiao +5
Spatially varying strained graphene can acquire interesting electronic properties because of the strain-induced valley-dependent gauge (pseudomagnetic) fields1,2. Here we report th…
