Messung der Exzitonenbildungszeit und der Elektronen- und Löcher-Tunnelzeiten in einer Doppelquantumstruktur
Abstract
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 6X10-12 cmhigh2/ps is obtained. The electron- and hole-tunneling times are determined simultaneously under the same sample conditions.
