About the Author

M. Jamal Deen completed a BSc degree at the University of Guyana (Guyana) and a PhD in Electrical Engineering and Applied Physics at Case Western Reserve University (USA). Professor Deen has been an assistant professor at Lehigh University, Bethlehem (USA) and was professor in the School of Engineering Science, Simon Fraser University, Vancouver (Canada). In 1999, he assumed his current position as Professor of Electrical and Computer Engineering, McMaster University, Hamilton (Canada). His current research interests include physics, modeling, reliability and parameter extraction of semiconductor devices; optical detectors and receivers, polymers and organic semiconductor devices, and low power, low-noise, high-frequency circuits. He is a Distinguished Lecturer of the IEEE- Electron Device Society, was awarded the 2002 Thomas D. Callinan Award from the Electrochemical Society, the Distinguished Researcher award, Province of Ontario and a Humboldt Research Award from the Alexander von Humboldt Foundation in 2006. In September 2008, he was awarded the prestigious Thomas W. Eadie medal by the Royal Society of Canada for his work on the modeling and noise of electronic and optoelectronic devices, with particular reference to silicon transistors and high-speed photodetectors.

Prasanta Kumar Basu obtained his BSc and his PhD from the University of Calcutta (India). He worked in the Institute of Radio Physics and Electronics, as a lecturer, then as a reader and finally as a professor. He served as the Head of the Department and he is now the Programme Coordinator of the Centre of Advanced Study in Radio Physics and Electronics at the University of Calcutta. Professor Basu worked as a Postdoctoral Fellow at the Catholic University, Leuven, Belgium, as an Alexander von Humboldt Fellow in Wuerzburg University, Germany and has been a visiting professor at McMaster University, Hamilton, Canada several times. Professor Basu’s research interests include semiconductor physics and devices, optoelectronics and optical communication, nanoelectronics and nanophotonics. He has more than 100 research publications in refereed journals and has authored a book Theory of Optical Processes in Semiconductors: Bulk and Microstructures.
