Attracting shallow donors: Hydrogen passivation in (Al,Ga,In)-doped ZnO

Masahiko Matsubara, Mozhgan N. Amini, Rolando Saniz +2

The hydrogen interstitial and the substitutional Al_Zn, Ga_Zn and In_Zn are all shallow donors in ZnO and lead to n-type conductivity. Although shallow donors are expected to repel…
