Deposição, caracterização e aplicação de filmes nanoestruturados de ZnO : biossensores de glicose e ureia
(2014) [Tesis]Este trabalho foi dedicado à produção e caracterização de filmes nanoestruturados de ZnO, depositado pelo método CBD (Chemical Bath Deposition). Trata-se de um método atrativo por ser simples, de baixo custo, por permitir ... -
Intermixing between HfO2 and GeO2 films deposited on Ge(001) and Si(001) : role of the substrate
(2011) [Artículo de periódico]Thermally driven atomic transport in HfO2 /GeO2/substrate structures on Ge 001 and Si 001 was investigated in N2 ambient as function of annealing temperature and time. As-deposited stacks showed no detectable intermixing ... -
Investigation of indirect structural and chemical parameters of GeSi nanoparticles in a silica matrix by combined synchrotron radiation techniques
(2012) [Artículo de periódico]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. ... -
Lift-off protocols for thin films for use in EXAFS experiments
(2013) [Artículo de periódico]Lift-off protocols for thin films for improved extended X-ray absorption fine structure (EXAFS) measurements are presented. Using wet chemical etching of the substrate or the interlayer between the thin film and the ...
