Broadband THz response of a resonantly excited high-density exciton gas

Not Accessible

Your library or personal account may give you access

Abstract

The density-driven crossover of electron-hole pairs from insulating to conducting states is observed via the internal 1s-2p exciton resonance. Decreasing interparticle distance induces strong shifts and broadening, and ultimately the disappearance of the excitonic resonance.
