Phys. Rev. B 48, 15449–15452 (1993)Confinement-enhanced biexciton binding energy in semiconductor quantum dotsReceived 19 July 1993; published in the issue dated 15 November 1993 Experimental observation of the ground-state biexciton transition in CdSxSe1-x quantum dots in glass is presented in a three-beam experiment, involving a probe, a pump, and a saturating laser pulse. The observed quantum-dot biexciton ground state has a strongly enhanced binding energy compared to the bulk as theoretically predicted. The biexciton binding energy is measured as a function of quantum-dot size and the results are compared with calculations. © 1993 The American Physical Society URL:
