Abstract

We report a modulation-doped multiquantum well structure which suppresses the usual ambient light effect associated with modulation doping. Ten GaAs quantum wells 300-Å wide are symmetrically modulation doped using Si δ doping at the center of 3600-Å-wide Al_0.1Ga _0.9As barriers. The low field mobility of each well is 4.0×10⁶ cm/V s at a density of 6.4×10¹⁰ cm^-2 measured at 0.3 K either in the dark, or during, or after, exposure to light. This mobility is an order of magnitude improvement over previous work on multiwells.
