Possible triplet superconductivity in MOSFETs

TL;DR

This paper proposes that recent experimental observations of insulator-to-conductor transitions in 2D electron systems could be explained by a spin-triplet, even-parity superconducting state, and suggests experiments to test this hypothesis.

Contribution

It re-analyzes a theory predicting triplet superconductivity in 2D systems in light of recent experiments and proposes experimental tests for this exotic state.

Findings

Observations are consistent with triplet superconductivity.

Predictions made for future experimental verification.

Supports the possibility of unconventional superconductivity in MOSFETs.

Abstract

A theory that predicts a spin-triplet, even-parity superconducting ground state in two-dimensional electron systems is re-analyzed in the light of recent experiments showing a possible insulator-to-conductor transition in such systems. It is shown that the observations are consistent with such an exotic superconductivity mechanism, and predictions are made for experiments that would further corroborate or refute this proposal.
