The catalytic activity of palladium deposited on alumina and silica–alumina for the
dehydrogenation of cyclo-hexane was studied. The introduction of sulfur-containing …

The presence of a parasitic surface film of 80 nm thickness has been observed by x-ray
reflectivity on the top of some p+ type porous silicon layers, related to a contamination of the …

X-ray reflectivity (XRR) was used to investigate the p−-and p+-type porous silicon (PS)
layers. For p−-type samples, a linear dependence of the thickness versus the anodization …

Porous silicon is a unique example of a porous material exhibiting the properties of a nearly
perfect single crystal. High resolution x-ray diffraction has been used to investigate thin p …

In this paper, we present a study on the porous silicon surface with the aim of filling porous
silicon layers with organics. We discuss on two processes used to remove the outer parasitic …

Mesoporous silicon layers, realised by electrochemical anodisation of p+ silicon substrates
were completely oxidised and then impregnated by Disperse Red 1 (referred to as DR1) …

All-mesoporous silicon microstructures were released with standard micromachining
processes. The extremely high porosity of the films allows control of the mechanical …

Porous silicon materials are currently under intense investigation for optoelectronic
applications. Spectroscopic ellipsometry (SE) was used to study the optical properties of …

Detailed investigations have been carried out into micromachining processes that will
facilitate scalable, complex and uniform porosity structures based on porous silicon (PS) …

The surface morphology and the structure of porous germanium layers obtained by chemical
etching of n-type single-crystal Ge (111) substrates with their subsequent annealing in …
