Transição semicondutor-metal em nanocristais de VO2 termoeletricamente ativada
(Universidade Federal de Santa Maria, 2015-05-26)
In this thesis, structural and electrical characteristics are investigated around the thermally
triggered semiconductor to metal transition in VO2 thin films. The films, the metallics
electrodes, as well as SiO2 buffer ...
Espectroscopia de impedância elétrica do VO2
(Universidade Federal de Santa Maria, 2010-01-18)
Impedance Spectroscopy has been performed at the metal-semiconductor transition of vanadium dioxide thin films. The samples have been deposited by reactive magnetron sputtering onto heated glass substrates. The crystallographic ...
Propriedades extrínsecas em filmes finos de VO2
(Universidade Federal de Santa Maria, 2010-08-31)
In earlier work done at the Laboratory of Magnetism and Magnetic Materials in
Santa Maria, spectroscopy measurements of electrical impedance between 100 kHz
and 1 GHz were a function of temperature in VO2 thin films along ...
