Abstract

Indium nitride (InN) thin films have been deposited on Si(1 0 0) and Pt(1 1 1)/Ti/SiO₂/Si(1 0 0) substrates by reactive r.f. magnetron sputtering. By using a plasma power of 25 W, nitrogen gas pressure of 5-7 mTorr and substrate temperature of 300-400 °C, InN films with (0 0 0 2) orientation were obtained. The relative permittivity and electrical resistivity of the InN film were calculated from the measured electrical impedance. The piezoelectric coefficient d₃₃ of the InN film was measured by a heterodyne interferometer and found to be 3.12 ± 0.10 pm V^-1.
