抄録

A method is proposed to precisely control the emission energy of semiconductor quantum dots (QDs) by the application of local strain due to volume expansion of a phase-change material (GeSbTe) upon amorphization. The feasibility of the method is experimentally demonstrated using photoluminescence (PL) spectroscopy of single InAs/InP QDs on which a GeSbTe thin film is deposited. A significant red-shift of the PL peak energy upon amorphization and subsequent recovery by recrystallization with laser annealing were observed.
