In the present paper, the inelastic mean free path (IMFP) of incident electrons is calculated as a function of energy for silicon (Si), oxides of silicon (SiO 2 ), SiO, and Al 2 O 3 in bulk form by employing atomic/molecular inelastic cross sections derived by semi-empirical quantum mechanical method developed earlier. A general agreement of the present results is found with the most of the available data. It is of great importance that we have been able to estimate the minimum IMFP which
