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…
Presence versus absence of charging energies in PbTe quantum dots
