La spectroscopie des electrons Auger nous a permis de suivre la cinetique de formation de la couche d'oxyde de beryllium a la surface d'un alliage Cu-...

In this work, we present Raman spectroscopy studies of the C=O stretching mode for various cholesteryl alkanoates in the polycrystalline, cholesteric,...

The present paper describes an experimental method that can be used to measure the flatband voltage value in MOS devices. The method is based on the d...

In Saharian regions, the erosion of glass by sand particles during sandstorms is a regular phenomenon. The progressive loss of matter on surface affec...

Using the microscopic definition of the Townsend coefficient and based on theoretical considerations related to the physical behaviour of electrons in...
