Microorganisms are living things that for the most part cannot be seen through the naked eye. They live on and among humans‚ as well as plants‚ animals‚ and all that is a part of the Earth.

silicon (Si) reacts with either water vapor (H20) or oxygen (O2) to form silicon dioxide‚SiO2 on the silicon surface. The reaction is represented by following equations: Dry oxidation: Si + O2 → SiO2 Wet oxidation: Si + 2H2O → SiO2 + 2H2 The oxidation process can be implemented through diffusion of either water or an oxygen species through the oxide already formed up which then reacts with the silicon at the Si-SiO2 interface. At high temperature
