中文摘要 | the intrinsic large electronegativity of o 2p character of the valence-band maximum (vbm) of zno renders it extremely difficult to be doped p type. we show from density functional calculation that such vbm characteristic can be altered by compensated donor-acceptor pairs, thus improve the p-type dopability. by incorporating (ti+c) or (zr+c) into zno simultaneously, a fully occupied impurity band that has the c 2p character is created above the vbm of host zno. subsequent doping by n in zno: (ti+c) and zno: (zr+c) lead to the acceptor ionization energies of 0.18 and 0.13 ev, respectively, which is about 200 mev lower than it is in pure zno. |
