Quantized Andreev conductance in semiconductor nanowires
Yichun Gao, Wenyu Song, Yuhao Wang +20
Clean one-dimensional electron systems can exhibit quantized conductance. The plateau conductance doubles if the transport is dominated by Andreev reflection. Here, we report quant…
SQUID oscillations in PbTe nanowire networks
Yichun Gao, Wenyu Song, Zehao Yu +18
Network structures by semiconductor nanowires hold great promise for advanced quantum devices, especially for applications in topological quantum computing. In this study, we creat…
Gate-tunable subband degeneracy in semiconductor nanowires
Yuhao Wang, Wenyu Song, Zhan Cao +20
Degeneracy and symmetry have a profound relation in quantum systems. Here, we report gate-tunable subband degeneracy in PbTe nanowires with a nearly symmetric cross-sectional shape…
Enhanced superconductivity in PbTe-In hybrids
Zuhan Geng, Fangting Chen, Yichun Gao +18
We report the realization of epitaxial indium thin films on PbTe nanowires. The film is continuous and forms an atomically sharp interface with PbTe. Tunneling devices reveal a har…
Reducing disorder in PbTe nanowires for Majorana research
Wenyu Song, Zehao Yu, Yuhao Wang +19
Material challenges are the key issue in Majorana research where surface disorder constrains device performance. Here, we tackle this challenge by embedding PbTe nanowires within a…
