Synopsis:
Zinc oxide (ZnO) is a compound semiconductor packed with unique chemical, mechanical, and electrical properties which make it a suitable material for various device applications. ZnO is extensively used in sensors including gas sensors, biological sensors, electro-mechanical sensors, and it is widely used in everyday sunblock creams due to the adsorption of harmful UV light. As it will be discussed, to fully utilized a semiconductor in device applications, two types of electrical conductivity, namely n-type and p-type are necessary and because of the challenges of p-type ZnO growth, its application are limitted. In this work, however, successful fabrication of high quality p-type ZnO is reported. Since silicon is the workhorse of semiconductor industry, ZnO films are grown on Si substrates. In this presentation material analysis of high quality ZnO thin films grown on silicon (Si) substrates along with fabrication of Si/ZnO junction devices are discusses. Also examples of practical and interesting applications of this technology will be included in the presentation.
About the Speaker:
Dr. Saeed Esmaili is a recent graduate of the A. James Clark school of Engineering at the University of Maryland in College Park. His thesis was focused on the fabrication of high quality wide gap semiconductors and their applications in microelectronics. He also holds a Masters (2007) and a Bachelors degree (2005) in Computer Science and Electrical Engineering from the University of Maryland. Prior to his immigration to the States back in 2001, he completed a Bachelors degree in Biomedical Engineering at the National University of Iran AKA Shahid Beheshti Univerisity of Tehran. Dr. Esmaili has also completed continuing education programs in advanced English, Physics, Computer Science and Mathematics at Georgetown University in Washington DC. During his studies, he has taught several courses in Physics, Mathematics, and Engineering. Dr. Esmaili is currently working as an operational research analyst. He also continues his research on the development of zinc oxide based microelectronic devices.
