An XRD measurement reveals the amorphous nature of the prepared samples. The SEM and Raman study confirm the presence of CNT in SeTe alloy. The diffused prime Raman bands (G and D) have been appeared for MWCNT/SeTe glassy alloy. The current versus voltage (I V) characteristics and DC conductivity measurement were carried out.
Deposition and Structural Characterization of Sn-SeTe Thin Films
TSeTe thin films are fabricated by using the thermal evaporation technique. In order to determine the structural and morphological properties of these films, XRD (X-ray diffraction), SEM (Scanning electron microscopy), EDXA (Energy dispersive X-Ray analysis), Raman Analysis, and AFM (Atomic Force Microscopy) measurements are carried out.
