Abstract:
1. A method of forming a chalcogenide comprising device comprising: forming a first conductive electrode material on a substrate; forming a metal doped chalcogenide comprising material over the first conductive electrode material, the chalcogenide comprising material comprising the metal and A forming a discontinuous layer of passivating material over portions of the outer surface of the metal doped chalcogenide comprising material; and depositing a second conductive electrode material over the metal doped chalcogenide comprising material and the passivating material, and forming the second conductive electrode material into an electrode of the device wherein the discontinuous layer of passivating material is sufficient to improve the uneven surface characteristic such that after subsequent deposition of the second conductive electrode material on the outer surface, the chalcogenide comprising material is protected from being etched.
