Electromagnetic wave detector and electromagnetic wave detector assembly

An electromagnetic wave detector comprising:

• a semiconductor layer;
• a first insulating film arranged on the semiconductor layer, and provided with an opening;
• a two-dimensional material layer that is electrically connected to the semiconductor layer in the opening, the two-dimensional material layer extending from above the opening to the first insulating film;
• a first electrode electrically connected to the two-dimensional material layer;
• a second electrode electrically connected to the semiconductor layer;
• a second insulating film being in contact with the two-dimensional material layer, and
• a control electrode connected to the two-dimensional material layer with the second insulating film interposed between the control electrode and the two-dimensional material layer,
• wherein
• the control electrode and the second electrode sandwich the semiconductor layer,
• the second insulating film covers the control electrode, and
• the two-dimensional material layer covers the semiconductor layer, the first insulating film and the second insulating film.
