摘要：

The bimolecular nature of exciton formation from free carriers is demonstrated experimentally in a GaAs asymmetric double-quantum-well tunneling structure. A bimolecular formation coefficient of 6 X 10(-12) cm2/ps is obtained. The electron- and hole-tunneling times are determined simultaneously under the same sample conditions.
