Neutralization of low energy Na scattered from InAs(001)
Haoshan Zhu, Chao Lian, Bryan M. Wong +1
The neutralization probability of low energy Na ions scattered from In- and As-rich InAs(001) surfaces is measured by time-of-flight spectroscopy. It is found that the neutra…
Cs adsorption on BiSe
Haoshan Zhu, Weimin Zhou, Jory A. Yarmoff
BiSe is a topological insulator whose unique properties result from topological surface states (TSS) in the band gap. The adsorption of Cs onto a BiSe surface is in…
Halogen adsorption and reaction with Bi(Se,Te) and Bi/Bi(Se,Te)
Haoshan Zhu, Weimin Zhou, Jory A. Yarmoff
BiSe and BiTe, and these same surfaces covered with Bi films, are exposed to Br and Cl in ultra-high vacuum. Low energy electron diffraction (LEED) and low…
Spatial Distribution of Topological Surface State Electrons in BiTe Probed by Low Energy Na Ion Scattering
Weimin Zhou, Haoshan Zhu, Jory A. Yarmoff
BiTe is a topological insulator whose unique properties result from topological surface states in the band gap. The neutralization of scattered low energy Na, which is…
The growth of bismuth on BiSe and the stability of the first bilayer
Haoshan Zhu, Weimin Zhou, Jory A. Yarmoff
Bi(0001) films with thicknesses up to several bilayers (BLs) are grown on Se-terminated BiSe(0001) surfaces, and low energy electron diffraction (LEED), low energy ion scat…
A detailed analysis of impact collision ion scattering spectroscopy of bismuth selenide
Weimin Zhou, Haoshan Zhu, Jory A. Yarmoff
Impact collision ion scattering spectroscopy (ICISS), which is a variation of low energy ion scattering (LEIS) that employs large scattering angles, is performed on Bi2Se3 surfaces…
Preparation of clean surfaces and Se vacancy formation in BiSe by ion bombardment and annealing
Weimin Zhou, Haoshan Zhu, Connie M. Valles +1
Bismuth Selenide (BiSe) is a topological insulator (TI) with a structure consisting of stacked quintuple layers. Single crystal surfaces are commonly prepared by mechan…
Spatial Distribution of Topological Surface State Electrons in BiSe Probed by Na Low Energy Ion Scattering
Weimin Zhou, Haoshan Zhu, Jory A. Yarmoff
BiSe is a topological insulator whose unique properties result from topological surface states (TSS) in the band gap. Low energy ion scattering can determine the proper…
Surface Structure of In Situ Cleaved Single Crystal Bi2Se3 Measured by Low Energy Ion Scattering
Weimin Zhou, Haoshan Zhu, Jory A. Yarmoff
Bismuth Selenide is a two-dimensional topological insulator material composed of stacked quintuple layers (QL). The layers are held together by a weak van der Waals force that enab…
Termination of Single Crystal Bi2Se3 Surfaces Prepared by Various Methods
Weimin Zhou, Haoshan Zhu, Jory A. Yarmoff
Bismuth Selenide (Bi2Se3) is a topological insulator with a two-dimensional layered structure that enables clean and well-ordered surfaces to be prepared by cleaving. Although some…
