Both the surface chemistry (measured through Auger spectroscopy) and the photoluminescence (PL) of p-Si are measured before and after the electron irradiation. A different behavior is observed on samples with various porosity. High porosity samples show surface charge accumulation during irradiation and PL degradation after treatment, while low porosity samples do not. This is interpreted in term of space charge effects on the p-Si surface that induce loss of surface passivation and, consequently, photoluminescence degradation. This finding can explain the measured electroluminescent properties of Schottky diodes formed by Au evaporation on p-Si.

The phenomenon results more pronounced for low temperature furnace heating than after rapid thermal annealing and for those elements having a larger component of interstitialcy diffusion mechanism.A close correlation was found between the trends of the anomalous dopant diffusion and the implant damage evolution analyzed by X-ray diffraction. This evolution takes place via interstitial cluster dissolution.

The influence of oxygen, carbon and boron segregation at grain boundaries and twin boundaries on ... more The influence of oxygen, carbon and boron segregation at grain boundaries and twin boundaries on the electrical activity of these defects has been investigated and demonstrated using SIMS, EBIC and LBIC measurements. It appears that invariably carbon and boron segregation induces strong electrical activity on extended defects, while simultaneous oxygen and carbon segregation or the sole oxygen segregation induces a variety of electrical effects, like bright contrast or double maxima figures. A preliminary discussion of these results is given.

From this point of view, the definition of a well-defined scale of acid-base strength and the use of a wide and well-equilibrated, appropriate set of liquids is very important. In the present paper some recent results are presented which are based on the mathematical approach discussed by Della Volpe and Siboni in previous papers. The treatment is developed as a list of questions, Frequently Asked Questions (FAQs), whose theoretical implications are discussed using numerical examples chosen from the literature. Some literature data, collected by the opponents of the acid-base theory and recently published, are re-analysed using these methods, showing that they constitute a well-defined set to calculate, with a good precision, the acidbase components of the considered materials and the interfacial energies of liquids used. The present paper is the premise of a second one, in which a set of contact angles data collected by the authors and by other researchers will be analysed following the principles discussed here.
