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…
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…
In situ tuning of dynamical Coulomb blockade on Andreev bound states in hybrid nanowire devices
Shan Zhang, Zhichuan Wang, Dong Pan +14
Electron interactions in quantum devices can exhibit intriguing phenomena. One example is assembling an electronic device in series with an on-chip resistor. The quantum laws of el…
Plateau regions for zero-bias peaks within 5% of the quantized conductance value
Zhaoyu Wang, Huading Song, Dong Pan +13
Probing an isolated Majorana zero mode is predicted to reveal a tunneling conductance quantized at at zero temperature. Experimentally, a zero-bias peak (ZBP) is expected…
Large zero bias peaks and dips in a four-terminal thin InAs-Al nanowire device
Huading Song, Zitong Zhang, Dong Pan +11
We report electron transport studies of a thin InAs-Al hybrid semiconductor-superconductor nanowire device using a four-terminal design. Compared to previous works, thinner InAs na…
