| Abstract(in English) | We have directly measured carrier tunneling times between vertically aligned double quantum dots (QDs) using time-resolved photoluminescence measurement. The vertically aligned double QD structure consists of the In_<0.9>Al_<0.1>As QDs layer, GaAs barrier layer and InAs QDs layer. The tunneling times were measured for the three different barrier thicknesses. The dependence of the tunneling time on the barrier thickness is in agreement with the Wentzel-Kramers-Brillouin approximation. The nonresonant tunneling rate between QDs is found to be suppressed to one-tenth of the tunneling rate between quantum wells. |
