ELECTROMAGNETIC WAVE DETECTOR, ELECTROMAGNETIC WAVE DETECTOR ARRAY, AND IMAGE SENSOR

Abstract: an electromagnetic wave detector includes a first ferroelectric layer, a two-dimensional material layer, a first electrode pair, and a second electrode pair. the first electrode pair includes a first electrode and a second electrode. the second electrode pair includes a third electrode and a fourth electrode. the first electrode pair and the second electrode pair are electrically connected to the two-dimensional material layer. the third electrode and the fourth electrode are disposed to face each other in a first direction perpendicular to a polarization direction of spontaneous polarization of the first ferroelectric layer. the first electrode and the second electrode are disposed to face each other in a second direction different from the first direction.
