In this work we derived the adsorption isotherms for non-dissociative and dissociative chemisorption of oxygen on a semiconductor surface. We extended the Wolkenstein theory for dissociative chemisorption and re-examined the basis that led to current

Potential barriers formed at the intergrain of polycrystalline metal-oxide semiconductors, such as tin oxide, present fluctuations that are usually ignored in the study of gas sensors responses. Fluctuations in the Schottky-type barriers arise from t

We have studied the dynamic scaling properties of a growth model in which the particle attachment probability is a function of surface curvature. Preferential incorporation of particles at protuberances (rather than over valleys) is followed by surfa

We investigated the power-law responses in two types of tin dioxide (SnO2) films: one made from nanosized grains and another from from very large grains, both under dry air. Experimental results revealed a significant dependence between the sensitivi

Halogen adsorption induces roughening of Si(100) producing pits and regrowth structures that depend on the type of adsorbed halogen and coverage. It is thought that this spontaneous roughening arises from steric repul- sions between adsorbates. Recen

The formation of two- and three-dimensional hillocks is regularly observed in Si(1 1 1) steps and Si(1 0 0) during wet etching. Frequently the resulting morphology consists of hillocks scattered on a landscape of limited roughness. Recently we propos

We derived a simple mean field model that accounts for the formation of hillock-and-valley patterns after etching in steady state. The mechanisms and their interrelations that lead to these patterns experimentally observed are described. Hillocks and

Surface grown by the deposition of rigid and wetting clusters has been investigated using Monte Carlo simulations in 1 + 1 dimensions. Dynamic scaling exponents were determined using the time evolution of the roughness, the local width, the height-he

With a solid-on-solid model, we show how adsorbates can induce surface roughening. Roughened surfaces exhibit pits and regrowth structures that have characteristic patterns that depend directly on the adsorbate coverage and on the strength and type o
