An overview of the properties of electron small polarons and bipolarons is given, which can
occur in the congruently melting composition of LiNbO 3 (LN). Such polarons influence the …

An overview of optical nonlinearities of small bound polarons is given, which can occur in
the congruently melting composition of LiNbO 3. Such polarons decisively influence the …

In this review article, we discuss photoluminescence phenomena mediated by polarons in
lithium niobate (LNO). At first we present the fundamentals on polaron states in LNO and …

Based on recent experimental evidence on the electronic and optical properties of Fe Li 2+
and Nb Nb 4+ in LiNbO 3: Fe, both strongly determined by their small polaron character, a …

Polarons in dielectric crystals play a crucial role for applications in integrated electronics and
optoelectronics. In this work, we use density-functional theory and Green's function methods …

Hole polarons and defect-bound exciton polarons in lithium niobate are investigated by
means of density-functional theory, where the localization of the holes is achieved by …

Transient absorption and photoluminescence are experimentally investigated in the
polaronic reference system lithium niobate, LiNbO (LN), with the aim to refine the …

A strongly temperature-dependent photo-induced transient absorption is measured in 6.5
mol% magnesium-doped lithium niobate at temperatures ranging from 45 K to 225 K. This …

Density-functional theory within a Berry-phase formulation of the dynamical polarization is
used to determine the second-order susceptibility χ (2) of lithium niobate (LiNbO 3). Defect …

The problem of the kinetic description of a light-induced, small-electron polaron population
decay in a lithium niobate crystal (LiNbO3, LN) doped with Fe is considered on the basis of …
