The disclosure relates to electronic devices and associated methods of manufacture including materials of the Group III/N. An exemplary device successively includes, from its base towards its surface: (i) a support substrate, (ii) a layer adapted to contain an electron gas, (iii) a barrier layer, and (iv) a superficial layer extending on at least one part of the surface of the barrier layer, wherein the superficial layer has an electrical field of which the current is controlled so that, in at least one first region of the superficial layer, the electrical field is weaker than in a second region of the superficial layer. |
