Title: Semiconductor superlattice material
Inventor: IWATA HIROSHI
IPC: H01L29/80
Filed: 1986-05-20
Abstract: PURPOSE:To transfer a current without impediment, by forming the energy position at the band end of a second semiconductor layer having no deep level deeper than the energy position of a deep level of a first semiconductor layer having a deep level. CONSTITUTION:Many of a first semiconductor layers 11 having a deep level and a second semiconductor layers 12 having no deep level are alternately laminated. The energy position at band end of the second layer 12 is formed deeper than the energy position of the deep level of the semiconductor layer 11. Then, in a state of thermal equilibrium, a carrier is not captured in the deep level of the semiconductor layer 11, but mainly exists in the semiconductor layer 12. There is no deep level in the semiconductor layer 12, so the carrier can move freely. Thereby the current can be transferred without impediment.
