The Handbook of Porous Silicon brings together the expertise of a large, international team of almost 100 academic researchers, engineers, and product developers from industry across electronics, medicine, nutrition and consumer care to summarize the field in its entirity with 150 chapters and 5000 references. The volume presents 5 parts which cover fabrication techniques, material properties, characterization techniques, processing and applications. Much attention was given in the the past to its luminescent properties, but increasingly it is the biodegradability, mechanical, thermal and sensing capabilities that are attracting attention. The volume is divided into focussed data reviews with, wherever possible, quantitative rather than qualitative descriptions of both properties and performance. The book is targeted at undergraduates, postgraduates, and experienced researchers

Thermoluminescence of Porous Silicon

Author: Valeriy Skryshevsky 


The characteristics of electronics states in porous silicon (PS) from measurements of thermoluminescence Thermoluminescence (TL) are presented. The observed shape of the TL peaks at low temperatures (4-250 K) is explained by quasi-continuous spectrum of the electron traps with activation energy in range of 0.03-0.4 eV. The high-energy peaks observed at 100-300 °C are associated with radiation-induced defects E′ (≡ Si •) and nonbridging oxygen hole centers (≡ Si − O •) that generated in insulating SiOx layer which covers the PS surface. Currently, the TL of PS is not exploited as a radiation dosimeter, due to the low activation energies of the traps and strong fading. Nevertheless, the observations of high temperature peaks of TL in oxidized PS, its biocompatibility and other properties, suggest a potential use of this material for in vivo dosimetry. An additional application could be the use of PS as a template for more established scintillation materials.
