Abstract

Highly conductive ZnO films were fabricated on p-GaN in a two-step process. First, zinc was thermally evaporated on p-GaN. Next, zinc film was oxidized in oxygen flow. To increase the conductivity of ZnO, nitrogen was introduced into zinc during its deposition. The above procedure proved successful in fabricating ZnO of the resistivity of ∼1×10-3Ωcm and resulted in ohmic contacts of resistivity ∼1×10-2Ωcm2 to low-doped p-GaN, and light transmittance of ∼75% in the wavelength range of 400-700 nm.
