ABSTRACTThe carrier recombination rate in high-quality FZ and Cz silicon substrates is studied by contactless infrared and microwave absorption techniques. Different surface treatments covering a wide range of surface recombination velocity have been used for the separation of bulk and surface recombination components and evaluating of the efficiency of passivation. Limitations of effective lifetime approach are analyzed specific for low and high injection level. Sensitivity limits of the techniques for iron contamination are discussed

ABSTRACTThe structure of aged porous silicon (PS) has been investigated using reflectivity, photoluminescence (PL), optical absorption and photoconductivity decay. An optical anisotropy in a perpendicular to surface direction is observed for PS samples below a critical porosity of 70%. The photostability of the PL spectra imply three different structures of PS, these should be attributed to quantum size structures, polymeric type structures and fluor-related structures. The absorption edge is deconvoluted into a band-to-band absorption with energy ranging between Eg = 1.6–2 eV and an absorption shoulder at hu ≤ Eg. The high energy PL band around 2.3 eV resembles that of fluoroindate glass. The observed rapid lifetime at high injection level is attributed to excitonic Auger-type recombination.

AbstractCurrent-voltage p-n junction characteristics have been analyzed mainly at low injection levels. The high injection level region of the I/V characteristic allows the possibility of determining basic parameters of the semiconductor material, like the bulk doping concentration and charge carrier lifetime. Based on a new theoretical model of the p-n junction characteristics, valid for both low level and high level regions, a new general equation of the p-n junction is presented. It can serve for parameter extraction of semiconductor devices.
