Abstract
Semiconductor self-assembled quantum dots (SAQDs) normally have zero-dimensional properties, but become coupled and acquire higher-dimensional character if the distance between the dots is small. Using photoluminescence spectroscopy under high hydrostatic pressure, we have obtained clear evidence for electronic coupling due to quantum-mechanical tunneling in stacks of InGaAs/GaAs SAQDs. We demonstrate that application of pressure allows controllable tuning and suppression of the electronic coupling. The effect originates from a pressure-induced increase in the effective mass of Gamma-electrons and a related increase in the interdot-barrier height. (c) 2005 American Institute of Physics.
