Presence versus absence of charging energies in PbTe quantum dots
Yuhao Wang, Lining Yang, Wenyu Song +18
Charging energy () is essential in quantum dot (QD) devices. Previous studies on PbTe QDs have reported both the presence and absence of . To resolve this ambiguity, we v…

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…
