摘要

Undoped n- and p-type tin monoxide (SnO) films have been selectively fabricated by pulsed laser deposition with a Sn target and careful control of oxygen partial pressure. The films are epitaxially grown in optimal growth conditions on yttria-stabilized zirconia (YSZ) substrates with out-of-plane and in-plane orientation relationships of (001)SnO//(001)YSZ and [110]SnO//[100]YSZ, respectively. Both Seebeck and Hall measurements show consistent results on the carrier types of the films. The electron Hall mobility is approximately 11 cm2/Vs at room temperature and the carrier activation energy is 0.14 eV for the n-type film. The growth at increased oxygen partial pressure yields p-type films, demonstrating the selective fabrication of both n- and p-type SnO films without doping.
