Highly Ti-doped ZnO films have been produced by a spin-casting sol-gel process. The spin-casted films show high in plane homogeneity and optical quality. However, when inspected in depth, the surface composition is Ti rich. We show that two possible annealing processes can be considered depending on the properties to exploit. To promote in-depth homogenization, thermal annealing processes have been applied. Meanwhile, the gradients can be exacerbated, thanks to a non-negligible surface sputterin...

Sequential plasma processes combined with specific lithographic methods allow for the fabrication of advanced material structures. In the present work, we used self-assembled colloidal monolayers as lithographic structures for the conformation of ordered Si submicrometer pillars by reactive ion etching. We explored different discharge conditions to optimize the Si pillar geometry. Selected structures were further decorated with gold by conventional sputtering, prior to colloidal monolayer lift-o...

Si-based metal–insulator–semiconductor (MIS) Schottky junction solar cells with the basic structure Al/Si/TiO2/Au were fabricated. This structure was modified by the addition of nanostructured porous silicon (nanoPS) layers and silver nanoparticles (AgNPs), resulting in devices with the following structures: Al/Si/nanoPS/TiO2/Au and Al/Si/nanoPS+AgNPs/TiO2/Au. The key performance parameters of the three MIS Schottky junction solar cells were determined, including spectral photocurrent response, ...

Abstract Porous silicon (PSi) offers extremely attractive optical, electronic and biofunctional properties for the development of biosensors. In the present work, we have studied the step by step sandwich biofunctionalization cascade of a PSi platform by near ambient pressure X-ray photoelectron spectroscopy (NAP-XPS) and, in parallel, we have developed a three electrode PSi device sensitive to changes in surface conductance. Prior to the NAP-XPS characterization, the organosilanization with gly...

Indium-tin oxide (ITO) is widely used as a transparent electrode for optoelectronic devices given its large transparency and high conductivity. However, the particular properties of this material greatly depend on the overall fabrication process. We report on the effect of four different postfabrication processes on ITO thin films grown by electron beam evaporation. More specifically, the effect on the overall properties of the evaporated ITO thin films of microwave plasma annealing, rapid therm...

Ti-doped ZnO thin films were obtained with the aim of tailoring ZnO film bioadhesiveness and making the optoelectronic properties of ZnO materials transferable to biological environments. The films were prepared on silicon substrates by sol–gel spin-coating and subsequent annealing. A Ti–O segregation limits the ZnO crystallite growth and creates a buffer out-layer. Consequently, the Ti-doped ZnO presents slightly increased resistivity, which remains in the order of 10–3 Ω·cm. The strong biochem...

Photonic and plasmonic systems have been intensively studied as an effective means to modify and enhance the electromagnetic field. In recent years hybrid plasmonic–photonic systems have been investigated as a promising solution for enhancing light-matter interaction. In the present work we present a hybrid structure obtained by growing a plasmonic 2D nanograting on top of a porous silicon distributed Bragg reflector. Particular attention has been devoted to the morphological characterization of...
