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 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 (LNT) solid solutions with the goal to probe the in…

Small electron polarons bound to interstitial tantalum defects in lithium tantalate
Anton Pfannstiel, Tobias Hehemann, Nils A. Schäfer +8
The absorption features of optically generated, short-lived small bound electron polarons are inspected in congruent lithium tantalate, (LT), in order to address th…
