Charge Separation of Dense 2D Electron-Hole Gases: Cold Exciton Ring Pattern Formation

Not Accessible

Your library or personal account may give you access

Abstract

A novel optically induced, in-plane separation of electrons and holes in modulation doped quantum wells leads to a long-lifetime supply of dense gas of thermalized cold excitons, forming ring emission patterns with large diameters.
