Abstract

It has been predicted that the ground state of the biexciton (two electron-hole pairs) in quantum dots should lie at an energy less than twice that of the lowest energy exciton state.1 The biexciton ground state has not been seen before as a result of broadening, both homogeneous and in homogeneous, which obscures the expected induced-absorption feature.
