Dr. Keyur Patel

I have received my M.Sc. and Ph.D. degree in 2006 and 2013 respectively from applied physics department, The M. S. University of Baroda, Vadodara, India. I am presently working as an Assistant professor in the Science and Humanities Department, BITS edu Campus, Varnama, Vadodara. I worked extensively in the areas of electrochromic thin film devices. My current areas of research includes semiconducting thin film devices and gas sensors. I have published 16 papers in international journals, national journals and conference proceeding.

Research paper thumbnail of Properties of RF magnetron sputtered indium tin oxide thin films on externally unheated glass substrate

The transparent and conducting ITO thin films were obtained on externally unheated glass substrate, without any post-heat treatment, and by varying the deposition process parameters such as the working pressure and the RF Power. The effect of the variation of the above deposition parameters on the structural, surface morphology, electrical, and optical properties of the thin films have been studied. A minimum resistivity of 2.36 × 10−4 Ω cm and 80% transmittance with a figure of merit 37.2 × 10−3 Ω−1 is achieved for the thin films grown on externally unheated substrate with 75 W RF power and 0.5 mTorr working pressure.

Research paper thumbnail of Barrier inhomogeneities in Au/CdSe thin film Schottky diodes

At room temperature, the characteristics obey the pure thermionic emission theory and the barrier height has been found to be 0.63 eV. The barrier heights decrease, while ideality factors increase with decrease in temperature. Further, the activation energy plot does not provide the expected Richardson constant and barrier height values. The abnormal behavior of the barrier heights and the ideality factors with respect to temperature as well as the difference between the barrier heights measured from I-V and those from C-V or flat band have been explored on the basis of barrier height inhomogeneities.
