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…

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…
Selective-Area-Grown PbTe-Pb Planar Josephson Junctions for Quantum Devices
Ruidong Li, Wenyu Song, Wentao Miao +17
Planar Josephson junctions are predicted to host Majorana zero modes. The material platforms in previous studies are two dimensional electron gases (InAs, InSb, InAsSb and HgTe) co…
Ballistic PbTe Nanowire Devices
Yuhao Wang, Fangting Chen, Wenyu Song +18
Disorder is the primary obstacle in current Majorana nanowire experiments. Reducing disorder or achieving ballistic transport is thus of paramount importance. In clean and ballisti…
Hard superconducting gap in PbTe nanowires
Yichun Gao, Wenyu Song, Shuai Yang +15
Semiconductor nanowires coupled to a superconductor provide a powerful testbed for quantum device physics such as Majorana zero modes and gate-tunable hybrid qubits. The performanc…
