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. The degeneracy is revealed in electron transport by the absence of a quantized plateau. Utilizing a dual gate design, we can apply an electric field to lift the degeneracy, reflected as emergence of the plateau. This degeneracy and its tunable lifting were challenging to observe in previous nanowire experiments…

By improving the nanowire-metal interface as well as the dielectric environment, it is shown that by consistently achieving conductance quantization at zero magnetic field, the contribution of orbital effects to the sub-band dispersion for different orientation of the magnetic field is studied.

An experimental study of one-dimensional (1D) electronic transport in an InSb semiconducting nanowire that can make the first plateau disappear, leaving a first conductance step of 2 e2/ h, indicative of a remarkable 2-fold sub-band degeneracy that can persist up to several tesla.

The 2-fold degeneracy in certain sub-band energies predicted by simulation due to structural symmetry is experimentally observed for the first time and the experimentally obtained sub- band energies match the simulated results, shedding light on both the energies of the sub-bands as well as the number of sub- bands populated per given gate voltage and diameter.
