Barrier-induced carrier localization effects in ordered/disordered/ordered quaternary quantum wells grown on GaAs substrates
Ribeiro, Evaldo; Bernussi, Ayrton Andre; Maltez, Rogério Luis; Carvalho Junior, Wilson; Gobbi, Angelo Luiz (2006) [Journal article]Optical and micro-structural properties of ordered/disordered/ordered InGaAsP quantum wells grown on GaAs substrates were investigated by photoluminescence spectroscopy, high-resolution transmission electron microscopy and ... -
Enhancement in interface robustness regarding thermal oxidation in nanostructured Al2O3 deposited on 4H-SiC
Corrêa, Silma Alberton; Marmitt, Gabriel Guterres; Bom, Nicolau Molina; Rosa, Aline Tais da; Stedile, Fernanda Chiarello; Radtke, Claudio; Soares, Gabriel Vieira; Baumvol, Israel Jacob Rabin; Krug, Cristiano; Gobbi, Angelo Luiz (2009) [Journal article]Experimental evidences of enhanced stability of Al2O3 /SiC structures following thermal annealing are presented. 5- and 40-nm-thick Al2O3 films evaporated on the Si- and C-terminated faces of 4H-SiC were annealed up to ... -
Investigation of indirect structural and chemical parameters of GeSi nanoparticles in a silica matrix by combined synchrotron radiation techniques
Gasperini, A. A. M.; Malachias, A.; Fabbris, Gilberto Fernandes Lopes; Kellermann, Guinter; Gobbi, Angelo Luiz; Avendaño Soto, E.; Azevedo, Gustavo de Medeiros (2012) [Journal article]The formation of GeSi nanoparticles on an SiO2 matrix is studied here by synchrotron-based techniques. The shape, average diameter and size dispersion were obtained from grazing-incidence small-angle X-ray scattering data. ...
