Schottky Diodes Based on the New Chitin Derivatives

OpenAlex İngilizce

Abstract New chitin derivatives were synthesized by the reactions of chitin with o-acetylsalicyloyl chloride and phthaloyl chloride and their structure was characterized by FTIR and 13C CP-MAS solid-state NMR spectroscopy and X-ray powder diffraction technique. Also, the thermal and surface properties of the chitin derivatives were investigated by thermogravimetric analysis and a scanning electron microscope. In addition, some electrical properties of the polymers were determined using Hall effect technique. Then, the Schottky diodes were fabricated by the formation of interlayers of chitin derivatives between Au metal and n-Si semiconductor, and the electrical and photoelectrical properties of the diodes were determined.
