Interplay of Quantum Size Effect and Tensile Strain on Surface Morphology of Sn(100) Islands
Bing Xia, Xiaoyin Li, Hongyuan Chen +16
The quantum size effect (QSE) and strain effect are two key factors influencing the surface morphology of thin films, which can increase film surface roughness through QSE-induced…
Fabrication and Characterization of the Moiré surface state on a topological insulator
Yi Zhang, Dang Liu, Qiaoyan Yu +19
A Moire superlattice on the topological insulator surface is predicted to exhibit many novel properties but has not been experimentally realized. Here, we developed a two-step grow…
Doping-induced Polyamorphic Transitions in Fluorite Oxides
Hao Yang, Qiaotong Luan, Qing Zhang +5
Fluorite oxides such as HfO exhibit rich and tunable phase behavior, making them promising candidates for next generation electronic devices. A key challenge is to design amorp…
Tunable topological edge states in black phosphorus-like Bi(110)
Chen Liu, Shengdan Tao, Guanyong Wang +12
We have investigated the structures and electronic properties of ultra-thin Bi(110) films grown on an s-wave superconductor substrate using low-temperature scanning tunneling micro…
