Abstract
The variation with applied bias of the electron charge density in the quantum well of a very asymmetric double-barrier resonant-tunneling st ructure is investigated using low-intensity photoluminescence and magn eto-optical techniques. The observation of inverted bistability phenom ena using optical techniques is reported. The very strong effects of i llumination intensity on both the electron charge density in the quant um well and the tunnel current in this system are analyzed.
