Study the Effect of Thickness on the Electrical Conductivity and Optical Constant of Co3O4 Thin Films	2017	8	.pdf	application/pdf	3127	163	69	[14] L tbR ⋅⋅ =ρ ……………………………………… (13) Where t is film thickness, b is electrodes width; L is distance between two Al electrodes. Then the conductivity (σ) of the films was determined by using the relation:- ρ =σ 1 c.d ………………………………………… (14) Results and Discussion a -Absorption Coefficient Fig (1) shows the variation of the absorption coefficient (α) of (Co3O4) films as a function of photon energy at various thicknesses (250, 350, 450, and 550) nm.	cache/iajs-519.pdf	txt/iajs-519.txt
