Abstract
ABSTRACT The Nebulized Spray Pyrolysis (NSP) process has created Sn-doped In2S3 thin films for various molar percentages on micro glass substrates. The structural, optical, morphological, and electrical characteristics of the thin films have all been studied. A cubic phase had formed in each of the deposited films, according to an X-ray diffraction analysis. The average transmittance of the films ranged from 75 to 96%, while the bandgap energies for direct permitted transitions varied from 2.32 to 2.77 eV. The Scanning Electron Microscopy (SEM) images showed the rock-plate type nanoparticles grown over the surface of the glass plates. The Hall effect study revealed the n-type conductivity and with a 3 mol% Sn-doped In2S3 thin film exhibited a carrier concentration of 17.36 × 1018 cm−3 with the lowest resistance of 21.6 Ω-cm.
