Abstract

We report on the observation of stable p-type conductivity in B and N co-doped epitaxial ZnO thin films grown by pulsed laser deposition. Films grown at higher oxygen partial pressure (∼10-1Torr) shows p-type conductivity with a carrier concentration of ∼3×1016cm-3. This p-type conductivity is associated with the significant decrease in defect emission peaks due to the vacancy oxygen (VO) and Schottky type-I native defects compared to films grown at low oxygen partial pressure (∼10-5Torr). The p-type conductivity is explained with the help of density functional theory (DFT) calculation considering off-stoichiometric BN1+x in the ZnO lattice.
