Abstract	The ionization energies of a hydrogenic donor in a GaAs- Ga1-xAlxAs cubical quantum dot system are obtained for various cross-sectional geometries. We have investigated the metal -insulator transition in such a system by considering the simultaneous effects of pressure and geometry. It is observed that, the ionization energies are increased due the geometry effect. Consecutively, the metal insulator transition couldn’t occur for lower concentration of donor impurities. We present the results for infinite confinement. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/27908
