Composition and Thickness Dependent Hall Coefficient, mobility and Carrier Concentration of Vacuum Evaporated Ag-Te Thin Films

Thin films of Ag-Te compound of varying composition and thicknesses have been formed on glass substrates employing three temperature method. The Hall voltage at different magnetic fields of various thin films was measured for different compositions and thicknesses of films. The Hall coefficient, mobility and carrier concentration of Ag-Te thin films of varying compositions and thicknesses were calculated. The phase change of Ag-Te thin films found composition dependent at room temperature and independent on thickness.
