Transparent conductive BaCuTeF thin films by pulsed laser deposition

ORAL

Abstract

Transparent p-type carrier conductive BaCuTeF thin films are reported. Undoped BaCuTeF films obtained \textit{in-situ} by pulsed laser deposition in UHV exhibit maximum conductivities of 50-55 S/cm on fused silica substrates. The polycrystalline films deposited at various temperatures up to 600$^{\circ}$C are single phase with optical band gap of about 3 eV and 70{\%} average transparency in the visible and near-IR optical ranges. BaCuTeF films deposited on single crystal MgO substrates are highly oriented.
