The Mechanism of Photohydrosilylation on Silicon and Porous Silicon Surfaces
Journal of the American Chemical Society, 2013Visible or UV light activates H-terminated Si surfaces because of the presence of a photogenerated hole in a Si-Si back-bond. Enhancing the lifetime of this hole at the surface increases reactivity. On the basis of photodynamics and electron transfer theory, the prevalence of two mechanisms of photoactivation (internal photoemission versus interband ...

Optical Properties of Porous Silicon
Solid State Communications, 1993Abstract The optical properties of porous Si films produced by electrochemical dissolution of Si are reviewed. From measurements of the optical absorption spectra an inverse relationship between the optical gap energy and the average nanoparticle size has been obtained demonstrating the quantum confinement of electron-hole pairs in Si ...

Silicon-on-Insulator and Porous Silicon
2004Silicon is by far the most widely used semiconductor material. It is abundant in the earth’s crust and relatively easy to convert into a high-purity single crystal. Unlike some other semiconductor materials, silicon is stable when heated at high temperature, and a well-behaved insulating and passivating material, silicon dioxide, can readily be grown ...

Luminescent Porous Silicon for Nanotheranostics
2016A variety of materials have been used in the treatment of disease or injury. A common definition of a ‘biomaterial’ or ‘biomedical material’ is a synthetic non-living material that replaces part of a living system or functions in intimate contact with living tissue. Humans have been using natural materials in medicine for hundreds of years. Some of the

Electrical Transport in Porous Silicon
2014The future development of porous silicon (PS)-based optoelectronic devices depends on a proper understanding of electrical transport properties of the PS material. Electrical transport in PS is influenced not only by each step of processing and fabrication methods but also by the properties of the initial base substrate.
