Improving the properties of Gum Arabic for Conversion in to Semiconductor

Abstract

The preparation of thin films of gum Arabic Acacia and Acacia on the rules of clean glass at room temperature were investigated the effect of vaccination with iodine them were studied distance between atoms and the angles between them was prepared solution of gum Arabic and iodine with different concentrations were determined higher wavelength happens with him absorption where he equal in gum acacia in Alhashab 360 350 Was preparing solutions of gum Arabic restaurant iodine concentrations were determined different gap energy each of them alone, and found that the concentration affects the energy gap and thus the conductivity.
