Abstract
The invention concerns a method for preparing a NIII-V semiconductor. According to the invention, the method includes at least one step of doping a semiconductor of general formula AlGaN, wherein the atomic number x represents the number between 0 and 1 with a p-type electron-accepting dopant, as well as a co-doping step with a codopant capable of modifying the structure of the valency band. The invention also concerns a semiconductor as well as its use in electronics or optoelectronics. The invention further concerns a device as well as a diode using such a semiconductor.
