Controlling Opto-electric Properties of Cadmium Stannate Thin Films Deposited by RF Sputtering

Category : Argon
Languages : en

Book Description
In this research, the optical and electrical properties of cadmium stannate thin films were studied in order to determine how these properties depend on the deposition and heat treatment conditions used during film formation. Trends in band gap energy, transmittance, mobility, resistivity and carrier density were studied, as well as the growth rate and the indices of refraction and extinction. Optical data was primarily measured using variable angle spectroscopic ellipsometry. In the process of acquiring this data, a procedure for accurately determining the optical properties using variable angle spectroscopic ellipsometry was developed. Ultimately, samples achieved the highest quality when deposited in 5% atmospheric oxygen at room temperature and heat treated at 600 °C in contact with a cadmium sulfide layer in an argon atmosphere. It was found that oxygen content and film thickness may affect the heat treatment process, while temperature treatments below 600 °C will not sufficiently induce crystallization. Further study should be given to controlling the cadmium sulfide diffusion rate in order to optimize carrier density and mobility.

Band Structure and Surface Effects in Cadmium Sulfide Photoemission Studies
Author: Neal Bert Kindig
Publisher:
ISBN:
Category : Cadmium sulfide
Languages : en
Pages : 182
Book Description
Photoemission measurements have been made on single crystals of cadmium sulfide which were cleaved and tested in high vacuum at photon energies between 7.2 and 11.6 eV. The electron affinity is found to be 4.8 eV. Additional measurements have been made in an extended range from 6 to 21.2 eV using surfaces cleaved in air or in low vacuum and tested in low vacuum. The apparatus for cleaving and measuring photoemission is described. Important features of the band structure are deduced from the energy distribution and quantum yield measurements. Two conduction band maxima are located about 6.7 and 8.2 eV above the top of the valence band. Two valence band maxima are located about 1.2 and 9.4 eV below the top of the valence band. The effects of surface conditions on photoemission from cadmium sulfide have been studied by comparing measurements made on samples cleaved in high vacuum with the corresponding results from surfaces prepared by other techniques.
