Fourier-based methods for removing mesh anomalies from angle resolved photoemission spectra
Shouzheng Liu, Erica Kotta, Yishuai Xu +6
Recent improvements to spatial resolution in angle-resolved photo-emission spectroscopy (ARPES) have made it common to perform measurements with a very brief dwell time, for the pu…
Spectromicroscopic measurement of surface and bulk band structure interplay in a disordered topological insulator
Erica Kotta, Lin Miao, Yishuai Xu +9
Topological insulators are bulk semiconductors that manifest in-gap massless Dirac surface states due to the topological bulk-boundary correspondence principle [1-3]. These surface…
Observation of a Topological Insulator Dirac Cone Reshaped by Non-magnetic Impurity Resonance
Lin Miao, Yishuai Xu, Wenhan Zhang +10
The massless Dirac electrons found at topological insulator surfaces are thought to be influenced very little by weak, non-magnetic disorder. However, a resonance effect of strongl…
Connection topology of step edge state bands at the surface of a three dimensional topological insulator
Yishuai Xu, Guodong Jiang, Janet Chiu +5
Topological insulators in the BiSe family manifest helical Dirac surface states that span the topologically ordered bulk band gap. Recent scanning tunneling microscopy meas…
