Increased Conductivity In Mg-Doped LiNbO3 By Reduction Of Electron-Phonon Coupling

Jorn Koppitz; Arthur I. Kuznetsov; Ortwin F. Schirmer; Manfred Wohlecke; Rico Worner; Christa Grabmaier

Le increased photoconductivity in highly Mg-doped LiNb03, suppressing optical damage is attributed partly to a decrease of the electron-phonon coupling, leading to enhanced carrier mobility. This is concluded from investigations of the dark conductivity of reduced LiNbO3, X-ray-induced luminescence, fundamental and below bandgap absorption and of the frequencies of the lattice modes.
