Probing PbTe-Pb nanowire devices with radio-frequency reflectometry
Xin-Yi Tang, Lin Li, Zezhou Xia +10
We report the implementation of radio-frequency (rf) reflectometry on selective-area-grown PbTe-Pb nanowire devices on a CdTe substrate. These nanowires are predicted to host Major…

Thickness-Induced Topological Phase Transition Investigated by Helicity Dependent Photocurrent in -Sn/CdTe(110)
Tengfei Liu, Xiyu Hong, Zhe Li +10
-Sn exhibits a rich topological phase diagram, yet experimental methods to tune and distinguish these phases remain limited. Here, we investigated the helicity-dependent photoc…

Universally optimizable strategy for magnetic gaps towards high-temperature quantum anomalous Hall states via magnetic-insulator/topological-insulator building-blocks
Zhe Li, Feng Xue, Xin-Yi Tang +4
Optimizing the magnetic Zeeman-splitting term, specifically the magnetic gap of the topological surface states (TSSs), is a crucial issue and central challenge in advancing higher-…
