A Stady on the Nano Structural, Electrical Properties of Tin and Chromium Nitride Using X-Ray Diffraction
Journal Title: Engineering and Technology Journal - Year 2025, Vol 10, Issue 02
Abstract
In this work the structural, optical and electrical properties of chromium nitride and tin were studied before and after the grinding process to know the mechanical effect on each of them using X-ray diffraction. A sample of chromium nitride compound was ground for an hour, as well as tin granules were sprinkled by an iron machine to obtain tin filings, then the tin filings were ground for two hours, and they were converted into a powder. The results of the X-ray diffraction measurements of the samples showed that the chromium nitride compound samples have a primitive hexagonal crystal structure, and the tin samples have a quaternary crystal structure. And there was a clear decrease in crystalline size for both samples, as it decreased by 34.74 nm / mol for chromium nitride compound samples, and for tin samples it was reduced by 6.15 nm / mol . The optical properties of the samples before and after grinding were studied by recording the transmittance and absorption spectra and the wavelength range (190-1100 nm). It was found that the absorbance decreases after grinding for all samples and the transmittance increases. The results showed that the optical energy gap values increased from 3.629 eV to 3.707 eV after grinding for chromium nitride and from 3.63 eV to 3.684 eV for tin. The results of the optical measurements also included calculating the optical constants represented by (the refractive index, the damping coefficient, the dielectric constant in its real and imaginary parts, and the optical conductivity), and it was found that There is a decrease in the values of the inertia and refractive index after grinding.
