Title: Photodetector having quantum wave interference layer
Inventor: KANO HIROYUKI
IPC: H01L31/10
Filed: 1999-12-17
Abstract: PROBLEM TO BE SOLVED: To increase a photodetection sensitivity and a respond speed by a pin junction, wherein the thickness of a quantum wave interference layer and a carrier confinement layer are specified. SOLUTION: In an (i) layer of a pin junction, quantum wave interference layers Q1-Q4, made by stacking a first layer W and a second layer B having a broader band width than the first layer W at a multiple cycle and carrier confinement layers C1-C3, are formed. The thicknesses of the first layer W and the second layer B are set at even-number times as large as one fourth that of the wavelength of the quantum wave of a carrier in each layer. In a boundary between the first layer W and the second layer B, a layer is formed which is sufficiently thinner than the first layer W and the second layer B and which causes rapid changes in an energy band.  Due to this structure, when electrons are excited by light in the carrier confinement layers C1-C3, the quantum wave interference layers are propagated by waves from an (n) layer to a (p) layer, to allow a photoelectric current to flow at high speeds.
