Abstract:
1. A method of forming a chalcogenide comprising device, comprising: forming a first conductive electrode material on a substrate; forming an amorphous chalcogenide comprising material to a first thickness over the first conductive electrode material, the chalcogenide material comprising A forming a metal comprising layer to a second thickness over the chalcogenide comprising material, said second thickness being less than, but not within 10% of a transition thickness of said metal comprising layer, said transition thickness being a thickness of said metal layer which, when diffused into said chalcogenide comprising material, transforms said chalcogenide comprising material from an amorphous to a crystalline state; irradiating said metal comprising layer such that at least some of the metal is diffused into the chalcogenide material; and forming a second conductive electrode over the chalcogenide comprising material.
