Title MILLIMETER WAVE AND FAR-INFRARED DETECTOR
Abstract

The invention provides a millimeter wave and far-infrared detector of extre me sensitivity and shorter response time. The detector comprises an input (1) f or introducing incident millimeter wave or far-infrared radiation (2) to a detector antenna

a semiconductor substrate (4) on which is formed a single-electron transistor (14) for controlling the current penetrating a semiconductor quantum dot (12)

and bo w tie antennas (6, 6a, 6b, 6c) for concentrating millimeter wave or far-infrared radiation (2) onto a semiconductor quantum dot that define a submicron space in the single - electron transistor (14). The quantum dot forming a two-dimensional electron system efficiently absorbs the concentrated radiation and maintains the resulting excitation state for more than 10 nanoseconds so that more than 1,000,000 electrons can be transported for a single photon absorbed.
