Síntese, reatividade e caracterização estrutural de haletos de telúrio e ariltelurenila com estados de oxidação incomuns ou mistos.
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2011-03-24)
This work presents a study related to the halogenation of diarylditellurides (RTe)2
in order to obtain tellurium and aryltellurenyl halides with unusual or mixed oxidation
states. Although regarded as essentially unstable, ...

(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2019-07-26)
This work presents the synthesis and detailed structural analysis of a series of new complex salts of organotellurium halides with an emphasis on exploring the versatility of the metallic character of the tellurium atom, ...
Crystal Growth, Structural Phase Transitions, and Optical Gap Evolution of CH 3 NH 3 Pb(Br 1-x Cl x ) 3 Perovskites
(American Chemical Society, 2019-01)
Chemically tuned inorganic-organic hybrid halide perovskites based on bromide and chloride anions CH 3 NH 3 Pb(Br 1-x Cl x ) 3 have been crystallized and investigated by synchrotron X-ray diffraction (SXRD), scanning ...
How far does the defect tolerance of lead-halide perovskites range? The example of Bi impurities introducing efficient recombination centers
(Royal Society of Chemistry, 2019-03)
One of the key properties of lead-halide perovskites employed in solar cells is the defect tolerance of the materials, in particular regarding intrinsic point defects, which mainly form shallow traps. Considering that high ...
