Title: Semiconductor layer structure
Inventor: FURUKAWA AKIO
IPC: H01L29/80
Filed: 1991-12-26
Abstract: PURPOSE:To reduce storage of electrons from the pinning level of a surface layer to a quantum well, in a semiconductor structure wherein AlSb is used for a potential barrier and InAs is used for a quantum well. CONSTITUTION:An InAs layer 1 which is too thin to have electric conductivity is formed on an AlSb layer 3 on the surface side of a quantum well structure wherein both sides of an InAs layer 2 are sandwiched by AlSb layers 3. By the above structure, surface pinning level is lowered as compared with the case that the surface layer is composed of AlSb or AlGaSb, and becomes nearly equal to the height of the first electron level of a quantum well layer, so that transfer of electrons from the surface pinning level to the quantum well are not caused. Since the InAs layer 1 on the surface is thin, the energy level of electrons is high, and electrons are not stored in the surface layer, thereby preventing electrically and optically adverse influence.

Thus, the brush does not come into contact with the pattern 8a, the grounding of the lower side of the resistance 2a is released, and the motor driver 3 stops the rotation of both input termonals. Next, when a color-selecting switch 7 is set on the opposite side, the brush 9 moves to the left end. Thus, when the brush 9 is at the left end by the motor 80 and when a fog lamp is, for example, white- colored, the brush moves to the right end, the color becomes yellow. While the brush is moved, the left end of the resistance 2a is grounded, and a relay 11a is deenergized by a transistor 14.
