We have studied by electrolyte electroreflectance and photoluminescence a GaAs/AIGaAs resonant tunneling structure (RTS) with a highly n-doped GaAs cap, before and after hydrogenation. We measured the amount of passivation of shallow donor states and of deep traps in the cap and found the approximat
