Generic quantized zero-bias conductance peaks in superconductor-semiconductor hybrid structures

Generic quantized zero-bias conductance peaks in superconductor-semiconductor hybrid structures

We show theoretically that quantized zero-bias conductance peaks should be ubiquitous in superconductor-semiconductor hybrids by employing a zero-dimensional random matrix model with continuous tuning parameters. We demonstrate that a normal metal-superconductor (NS) junction conductance spectra can be generically obtained in this model replicating all features seen in recent experimental results. …
