Bismuth tellurite, Bi2TeO5, here labeled BTeO has a lot of properties like improper
ferroelectricity, photochromic, photorefractive, with two optical axes large optical window and …

We report on optical and electrical measurements contributing for a better characterization of
the relevant properties of undoped Bi 2 TeO 5. Optical absorption, dark conductivity …

Single crystals of bismuth tellurite (Bi 2 TeO 5) were grown by a double crucible Czochralski
method at different pulling and rotation rates, ranging from 0.1 mm/h to 0.8 mm/h and from 5 …

This work presents the systematic results of studies concerning the sintering of the
Bi12TiO20 (BTO) aiming the production of transparent ceramic samples. All that because the …

Nanocrystalline Bi2Te3 thin films of 800 nm thickness synthesized via a thermal evaporation
method were annealed at various temperatures, which induced notable changes in both …

Bi12TiO20 (BTO) single crystals nominally pure and doped with ruthenium are grown by top-
seeded solution growth method. The effect of ruthenium concentration on optical and …

We report on the presence of a strong photovoltaic effect on nominally undoped
photorefractive Bi 2 TeO 5 crystals and estimated their Glass photovoltaic constant and …

Abstract Thin films of Bi 2 Te 3 alloy were grown by vacuum thermal evaporation (VTE) and
pulsed laser deposition (PLD) techniques. The growth was conducted on clean substrates of …

Bismuth tellurite has a unique feature, a long-living (years) photorefractive memory that
develops in the four-wave mixing process without fixing. Single crystals of Bi2TeO5 were …

Abstract Photorefractive Bi12TiO20 single crystals of high optical quality were grown in a
resistive heating furnace from high temperature nonstoichiometric (10: 1) solutions of Bi2O3 …
