Abstract
Hydrogen irradiation leads to the passivation of the electronic activity of nitrogen in Ga(AsN), thus allowing a fine tuning of the material optical properties. Here, some recent results on the effects that hydrogen irradiation has on the electronic properties of diluted III-N-V alloys are presented. In Ga(AsN), both the increase in the electron effective mass and exciton wave function localization induced by nitrogen are reversed in a fully controllable manner by hydrogen irradiation. In Ga(PN), hydrogen widens the band gap and exposes gradually in the gap nitrogen complex states formerly resonant with the conduction band.
