Large Andreev bound state zero bias peaks in a weakly dissipative environment

Plateau regions for zero-bias peaks within 5% of the quantized conductance value $2e^2/h$

“…This work is from a single device whose quality is an improvement over our previous one [14]. Besides the 'end-to-end' correlation experiment to reveal gap-closing-reopening [39][40][41], future devices on 'single-terminal' experiments could aim at 1) looking for zero-bias peak-to-dip transition near 2e 2 /h with better tolerance [14,16,19]; 2) using a strongly dissipative probe to reveal quantized ZBPs and suppress non-quantized ones [42][43][44][45][46]; 3) looking for ZBP quantization in potentially better material systems [47,48]. The device conductance G as a function of V was directly calculated by dI/dV .…”
