We have evaluated the electric characteristics of an organic surfactant material, n-Cethyl-trimethyl-ammonium Bromide (C16TAB) to fabricate the p-n homo-junction. This C16TAB was dissolved in the pure water, where the potassium iodide (KI) was added. The impurities adaptation has been processed in this mixed solution with the application of voltage. The KI is ionized in the water and the potassium ion is moved to the negative electrode and the iodine ion to the positive electrode. We collected the solution in the vicinity of both electrodes separately, and dried it to fabricate the samples. We measured the resistivities of both samples which were in the range of 10+3Ωcm. Both materials were contacted, and we measured the current-voltage (I-V) characteristics. We have obtained the I-V characteristics similar to a p-n homo-junction.
