Dynamics of the Mott Transition in CuCl with Subpicosecond Time Resolution

摘要: It is well known that a strongly excited semiconductor crystal may become partly metallic, due to the formation in medium of dense plasma free electron-hole pairs. This phase represents lowest electronically state crystal, as long carriers density n exceeds critical value nc. If falls below nc, system reverts an insulating (excitonic) consisting correlated The complete understanding this Mott-like transition, particularly its dynamical aspect, great interest, both from fundamental point view for potential applications, e.g. fast switching devices.
