# Scaling of Majorana Zero-Bias Conductance Peaks

## TL;DR

This paper experimentally investigates how Majorana zero-bias conductance peaks scale with magnetic field, tunnel coupling, and temperature in semiconductor-superconductor structures, confirming theoretical predictions and revealing universal scaling behavior.

## Contribution

It provides the first detailed experimental analysis of the scaling behavior of Majorana zero-bias peaks across multiple parameters, aligning with theoretical models.

## Key findings

- Conductance peaks scale proportionally with tunnel coupling.
- Peak conductance saturates at 2e^2/h.
- Scaling function collapses data across parameters.

## Abstract

We report an experimental study of the scaling of zero-bias conductance peaks compatible with Majorana zero modes as a function of magnetic field, tunnel coupling, and temperature in one-dimensional structures fabricated from an epitaxial semiconductor-superconductor heterostructure. Results are consistent with theory, including a peak conductance that is proportional to tunnel coupling, saturates at $2e^2/h$, decreases as expected with field-dependent gap, and collapses onto a simple scaling function in the dimensionless ratio of temperature and tunnel coupling.
