Double quantum dots with quenched charging energy in PbTe nanowires
Seth Byard, Maksim Gomanko, Adam Raynolds +4
We investigate double quantum dots defined by electrostatic gating in semiconductor PbTe nanowire devices. We perform transport measurements to obtain charge stability diagrams dis…

Apparent fractional charge signatures in PbTe quantum dots due to capacitively coupled charge trap dynamics
Seth Byard, Maksim Gomanko, Sergey M. Frolov
We report the observation of fractional shifts in the experimental stability diagrams of PbTe nanowire quantum dots. Although this behavior may appear to suggest fractional charge…
