3/2 fractional quantum Hall plateau in confined two-dimensional electron gas
3/2 fractional quantum Hall plateau in confined two-dimensional electron gas
Abstract Even-denominator fractional quantum Hall (FQH) states, such as 5/2 and 7/2, have been well known in a two-dimensional electron gas (2DEG) for decades and are still investigated as candidates of non-Abelian statistics. In this paper, we present the observation of a 3/2 FQH plateau in a single-layer 2DEG with …
