Disorder suppression and precise conductance quantization in constrictions of PbTe quantum wells

G. Grabecki, J. Wrobel, T. Dietl +7

Conductance quantization was measured in submicron constrictions of PbTe, patterned into narrow,12 nm wide quantum wells deposited between Pb${}_{0.92}$Eu${}_{0.08}$Te barriers. Becaus…
