“…Along with doping, an alternative approach to increasing the electrical conductivity of the crystals is annealing in a reducing environment (vacuum, hydrogen, nitrogen or inert atmosphere) [57][58][59][60][61][62]. Chemically reduced crystals become almost transparent, with a wide optical absorption band having a maximum at 2.5 eV which is attributed in literature to bound bipolarons [58,63]. It has been found recently [7] that local switching of "head-to-head" CDW domain structures in LN crystals after reduction annealing provides for efficient control of AFM probe / CDW point contact conductivity.…”

“…Изучению диффузии ионов Li + , Nb 5+ и O 2− , а также ионов примесей в кристаллах НЛ уделяется большое внимание [5,[7][8][9][10][11]. Известные результаты изу-чения диффузии кислорода в НЛ, полученные пу-тем исследования профиля изотопного обмена (O 18 /O 16 exchange) или исследования электрической проводимо-сти (dc conductivity) представлены в табл.…”
