<P>PROBLEM TO BE SOLVED: To provide an infrared light detector capable of further enhancing sensitivity with respect to infrared light. <P>SOLUTION: By the infrared light detector 100, since a single first electronic region is divided, a plurality of first electronic regions 10 which are electrically independent of each other and arranged in a specified direction are formed. An external electron system which is the electric connection destination of each first electronic region 10 in a connection state is configured such that the electronic energy level of the excitation subband of each of the plurality of first electronic regions 10 in a shut-off state becomes sufficiently higher than a Fermi level in each second electronic region 20 facing each first electronic region 10 in a conduction channel 120. <P>COPYRIGHT: (C)2011,JPO&INPIT |
