Defect-related Anomalous Mobility of Small polarons in Oxides: the Case of Congruent Lithium Niobate

Anton Pfannstiel, Mirco imlau, Marco Bazzan +1

Polarons play a major role in the description of optical, electrical and dielectrical properties of several ferroelectric oxides. The motion of those particles occur by elementary…

Long-lived, pulse-induced absorption in $LiNb_{1 - x} Ta_{x} O_{3}$ solid solutions: the case of three intrinsic defect sites for electron localization with strong coupling

Niklas Dömer, Julian Koelmann, Mira Hesselink +6

Femto-/nanosecond pulse-induced, red and near-infrared absorption is studied in $LiNb_{1 - x} Ta_{x} O_{3}$ (LNT) solid solutions with the goal to probe the in…
