Lecture 64: An Introduction to Zinc Oxide: Material Analysis, Growth, and Device Fabrication

When: Thursday August 8, 2013 – 7:30 PM
Where: Montgomery Community College (Rockville Campus) – Humanity Building (HU), Conference Room 009 (Get Directions, Campus Map )

Speaker: Saeed Esmaili., Ph.D.
Language: English

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.

Speaker: Leili Parsa, M.D.
Language: English

Synopsis:

Arthritis means joint inflammation. This presentation will cover the clinical manifestations, diagnosis and management of the two most common types of arthritis, osteoarthrits and rheumatoid arthritis.Osteoporosis is another common disorder, particularly in women. The screening criteria, risk factors, diagnosis and treatment of osteoporosis will also be discussed.

About the Speaker:

Dr. Leili Parsa is a board certified internist and a clinical fellow in rheumatology at Washington Hospital Center. Dr. Parsa received her medical doctorate (M.D.) at Tehran University of Medical Sciences in 2005 with honor. Following completion of her M.D., she joined a group of scientists in the Department of Cell and Neurobiology University of Southern California Los Angeles, California. She characterized structure of duct system of rabbit lacrimal glands and their role in making tear. She also investigated an animal model of Sjogren, an autoimmune disease resulting in dryness of mouth and eyes. Dr. Parsa completed her residency in Internal Medicine at the Union Memorial Hospital of University of Maryland in 2011. Dr. Parsa’s areas of clinical expertise are autoimmune disorders including systemic lupus erythematosis, vasculitis and arthritis. Dr. Parsa’s current research is focused on novel therapeutic strategies targeting rheumatoid arthritis.

Speaker: Dr. Aram Hessami
Language: Farsi

Synopsis:

What does the Myth of Rustam reveal about the Iranian psyche? Is this myth a unique cultural narrative or a universal human experience? Could it be both? Offering an interpretive understanding of this myth, the talk will explore the tension between the particular and the universal. Through the analysis of this myth, I will explore the post-modern approach to the understanding of this myth and what myths in general tend to disclose about human beings.

About the Speaker:

Dr. Aram Hessami is a professor of Political Science and Philosophy at Montgomery College in Rockville Maryland. He received his BA, MA, and Doctorate in Political Science from The George Washington University in 1993. Dr. Hessami’s specialization is in Western Political Thought and Post-modern philosophy. His research and publications are focused on Democratic Transition, Discourse Theory and Social Change. He co-edited a book, Contemporary Social Discourse. He has presented his papers and ideas in various colleges and universities including University of Massachusetts, University of Boston, University of South Carolina, University of Maryland Baltimore County, Baltimore School of Law, and The George Washington University. Dr. Hessami is on the Board of Directors and a vice-president of Iranian Academic & Professional Association. He is a on the Board of Damavand Cultural Society. Dr. Hessami is one of the founders and the Director of Institute for Advanced International Studies in Washington D.C.
