Estudo da transição cristalográfica em filme fino de VO2 por difração de raios-x
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2011-03-28)
In one sample, X-Ray diffractions have been measured as a function of the temperature, in
order to follow the crystallographic transition experienced by VO2 near 68ºC. The results have
been analysed with the aide of a ...
Estudo estrutural da fase modulada dos compostos mistos K2MOxW(1-x)O4 por difração de Raio X
(Universidade Federal de Minas GeraisUFMG, 2007-03-16)
The potassium molybdate (K2MoO4) and potassium tungstate (K2WO4) have been studied since middle sixties. Despite the great number of published works on the crystallographic structure of such compounds, some facts are still ...
