Abstract
This paper discusses a quantum-mechanical metal-insulator transition t hat occurs in an anisotropic electron-hole system with the electrons a nd holes separated and confined to a double quantum well. The critical concentration n(c) of carriers in the system above which the excitoni c (insulating) phase becomes an electron-hole (metallic) phase is inve stigated, along with its dependence on the distance between wells D.
