p-Type ZnO Thin Films Formed by CVD Reaction of Diethylzinc and NO Gas

Abstract
We discuss the use of nitric oxide (NO) gas to dope ZnO p-type films, fabricated using metallorganic chemical vapor deposition (CVD) reaction of a Zn metallorganic precursor and NO gas. In this reaction, NO gas is used to supply both O and N to form a N-doped ZnO (ZnO:N) film. Auger electron spectroscopy analysis indicated that, under Zn-rich condition, the N concentration in the film is readily detectable, with the highest concentration being atom %. For concentrations greater than 2 atom %, the films are p-type. The carrier concentration varies from to and the mobility is approximately The minimum film resistivity achieved is © 2003 The Electrochemical Society. All rights reserved.
