92 Electrical Optical and Structural properties of SnO2 Sb thin films for solar cell application Mehran Samaee m samai@ph iut ac ir Date of Submission 2013 23 01 Department of physics Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Supervisors Dr Hadi Salamati salamati@cc iut ac ir Abstract In this study the effect of substrate temperature on Antimony doped Tin Oxide SnO2 Sb thin films which were deposited by Pulsed Laser Deposition PLD method was investigated Thin films were deposited at Room temperature 200 300 400 and 600oC and on Quartz glass and Silicon 100 The X ray diffraction XRD patterns show tetragonal rutile structure was formed above 300oC FESEM images show smooth samples surface Resistivity Hall mobility and carrier concentration have been measured by Van der Pauw method Deposited samples at Room temperatures are almost by increasing the substrate temperature the electrical resistance insulator It was found that the of changes resistivity depend on Hall mobility carrier concentration and crystallite size UV Vis spectra of the samples show a high transparency in visible region Band gap of the samples were measured to be between 3 26eV to 3 18eV It was reduced by increasing substrate temperature Hall mobility and crystallite size The Photoluminescence PL results indicated that conduction mechanism of the system changes by substrate temperature Fourier transform infrared spectroscopy FTIR investigation show the chemical properties were in consent with others results PDF created with pdfFactory trial version www pdffactory com
