Abstract
An electromagnetic wave detector includes a semiconductor layer, a two-dimensional material layer electrically connected to the semiconductor layer, a first electrode electrically connected to the two-dimensional material layer without the semiconductor layer interposed therebetween, a second electrode electrically connected to the two-dimensional material layer with the semiconductor layer interposed therebetween, and a ferroelectric layer in contact with at least a part of the two-dimensional material layer.
Claims31
An electromagnetic wave detector comprising:
- a semiconductor layer;
- a two-dimensional material layer electrically connected to the semiconductor layer;
- a first electrode electrically connected to the two-dimensional material layer without the semiconductor layer interposed therebetween;
- a second electrode electrically connected to the two-dimensional material layer with the semiconductor layer interposed therebetween;
- and
- a ferroelectric layer,
- wherein the two-dimensional material layer includes a first portion that is electrically connected to the semiconductor layer, a second portion that is in contact with the first electrode, and a third portion electrically connecting the first portion to the second portion, and
- the ferroelectric layer is in contact with at least one of the first portion and the third portion of the two-dimensional material layer, or is disposed at a distance from the two-dimensional material layer and overlaps with at least a part of the two-dimensional material layer.
