The Adsorption and Desorption of Oxygen on CdZnTe (111)B-(2 × 2) Surface
TL;DR: In this paper, the surface work function of CdZnTe(111)B-(2×2) decreases after the oxygen exposure, and futher reduces after annealing.
Surface State at bar K Point of Surface Brillouin Zone on Cu{111} Surface
TL;DR: In this paper, the electronic structure of the Cu{111} surface along the line of surface Brillouin zone (SBZ) was studied using synchrotron radiation angle-resolved photoemission.
Topological insulator Bi2Se3 thin films grown on double-layer graphene by molecular beam epitaxy
Can-Li Song,Yi-Lin Wang,Yeping Jiang,Yi Zhang,Cui-Zu Chang,Lili Wang,Ke He,Xi Chen,Jin-Feng Jia,Yayu Wang,Zhong Fang,Xi Dai,Xincheng Xie,Xiao-Liang Qi,Shou-Cheng Zhang,Qi-Kun Xue,Xucun Ma +16 more
TL;DR: In this paper, the authors identified the Se-rich condition and temperature criterion for layer-by-layer growth of epitaxial Bi2Se3 films without doping and achieved a defect density of 1.0\pm 0.2x1011/cm2, and become a bulk insulator at a thickness of 10 quintuple layers.
Atomically flat superconducting NbN thin films grown on SrTiO3 (111) by plasma-assisted MBE
Guan-Yong Wang,Zhen Zhu,Xin-Yi Yang,Lu Dong,Hai-Yang Ma,Hao-Hua Sun,Ai-Min Li,Dandan Guan,Dong Qian,Canhua Liu,Yaoyi Li,Jin-Feng Jia +11 more
TL;DR: Using scanning tunneling microscopy and in situ reflection high energy electron diffraction, the authors investigated the surface structure of epitaxial NbN thin films on the SrTiO3 (111) substrate.
Identifying Charge States of Molecules with Spin-Flip Spectroscopy
Ying-Shuang Fu,Ying-Shuang Fu,Tong Zhang,Tong Zhang,Shuai-Hua Ji,Shuai-Hua Ji,Xi Chen,Xucun Ma,Jin-Feng Jia,Qi-Kun Xue,Qi-Kun Xue +10 more
TL;DR: The charged and neutral states have different spin structures and therefore exhibit different features associated with the spin-flip processes in tunneling spectra, demonstrating a general approach for detecting the charge states at the nanometer scale in a more straightforward manner than using indirect information.
