Defect Induced P-type Conductivity in Zinc Oxide at High Temperature: Electron Paramagnetic Resonance Spectroscopy

Abstract

High-temperature electron paramagnetic resonance (EPR) measurements were applied to ZnO nanocrystalline (50 nm) sample, synthesized via solid co-precipitation method, in order to understand the behavior of intrinsic defect centers at high temperatures. It has been observed that the defect centers on the surface play a crucial role on the conductivity behavior of ZnO. Above 300 °C only surface defects can be visible in EPR spectra for ZnO nanocrystals which indicate p-type conductivity.
