Filmes de diamante não-dopados e dopados: um estudo sistemático usando espectroscopia Raman
(Universidade Federal de São Carlos, 2004-11-17)
Diamond films grown by both hot filament (HFCVD) and microwave-plasma (MW-CVD) assisted chemical vapor deposition were investigated. Raman spectroscopy, scan-
ning electron microscopy and X-ray di¤raction were employed ...
Dispersão dielétrica em materiais ferroelétricos.
(Universidade Federal de São Carlos, 2004-12-13)
In the last decades, the high frequency dielectric response has been one of
the most studied issues in the ferroelectricity area. The main dielectric
characteristic is the strong dependence of the dielectric parameters ...
O papel da interação elétron-elétron no regime Hall quântico interio.
(Universidade Federal de São Carlos, 2004-04-02)
Experimental and theoretical studies of the aspects of particle-like and collective behavior
of electrons in the proximity of the edges of two-dimensional (2DES) and quasi-one-dimensional
(Q1DES) systems, named quantum ...
