The effect of Incorporation Salt and graphite on the relative permittivity,refractive index and capacitance for porous silicon

Abstract

In the present research some properties of porous silicon prepared by photo electro chemical etching process with different etching time (5,10,15)min, were studying dependence of these properties on the etching rate too. The relative permittivity, refractive index and capacitance for porous silicon were calculated were calculated for porous silicon exposure to ambient air, embedding with graphite, salt, respectively , and in the anther hand the search study theoretically, porous silicon and graphite, porous silicon and salt which made comparison for the results with matlab program assisted for mixing porous silicon and graphite and porous silicon and salt.
