摘要

Method of preparation of a substrate made of zno all or part of a semi - insulating or p-type doped, from a substrate made of zno with n type doping, in which are placed in contact with the substrate made of zno n doped with a molten salt is selected from among the anhydrous sodium nitrate, and lithium nitrate, potassium nitrate and rubidium nitrate melted anhydrous. The substrate, in particular in the form of a thin layer or nanowires prepared by this process, of the zno or gan may also be grown epitaxially on this substrate. Electronic device, opto-electronic or electro-optical such as a light-emitting diode (led) comprising the substrate.
