Abstract
PURPOSE:To improve a detection capability by a method wherein a tunnel barrier region, which can selectively control a flow of carriers created by a thermal excitation and an optical excitation, is formed in the transition region of a P-N junction. CONSTITUTION:A p-type Hg1-xCdxTe layer 2 and then an Hg1-yCdyTe layer 3 are built up by an epitaxial growth method on a CdTe substrate 1. The relation between (x) and (y) conforms to x<y. Then a p-type Hg1-xCdxTe layer 4 is again built up and, in a part of it, an n-type Hg1-xCdxTe region 4 is formed so as to come close to the layer 3. A ZnS protective film 5 is formed on the surface of the region 4 and an In electrode 6 for taking out a signal is attached to a part of it. As infrared radiation enters from the substrate side, it reaches the P-N junction region of the layer 2 almost without being absorbed and electron-positive holes are produced and electrons begin to be accumulated in a triangle potential region formed before the barrier. However, the blocking capability of the barrier is degraded by an electron accumulation effect and an energy rise effect and the decrease of a signal electron flow can be suppressed.
