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…
Strong enhancement of g-factor in PbTe-Pb hybrid nanowires
Shan Zhang, Wenyu Song, Zonglin Li +17
We report large Lande g-factors observed in PbTe-Pb hybrid nanowires. The g-factor can reach 83, significantly larger than those in bare PbTe nanowires (typically below 20). We att…
Anisotropy of PbTe nanowires with and without a superconductor
Zonglin Li, Wenyu Song, Shan Zhang +17
We investigate the anisotropic behaviors in PbTe and PbTe-Pb hybrid nanowires. In previous studies on PbTe, wire-to-wire variations in anisotropy indicate poor device control, posi…
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…
