Picture

D.L. Pulfrey received the B.Sc. and Ph.D. degrees in electrical engineering from the University of Manchester, England in 1965 and 1968, respectively. Since 1969 he has been on the faculty in the Electrical Engineering Department at the University of British Columbia, Vancouver, B.C., Canada.

He teaches and researches in the area of semiconductor devices. He has received awards for his teaching at the university-, provincial- and international-levels: inaugural winner of UBC's Teaching Prize for Engineering in 1990; the 2009 Teaching Award for Excellence in Engineering and Geoscience Education from the Association of Professional Engineers and Geoscientists of British Columbia; the 2009 Education Award from the IEEE Electron Devices Society. He has received recognition for his research work by being made Fellow of IEEE (2000) and the Canadian Academy of Engineering (2002).

He has written 3 books: "Understanding Modern Transistors and Diodes", which is to appear in February 2010; "Introduction to Microelectronic Devices" in 1989 with Garry Tarr; "Photovoltaic Power Generation" in 1979. He has written book chapters on heterojunction bipolar transistors for Wiley's Encyclopedia of Electrical and Electronic Engineering (1999) and for Roblin and Rohdin's "High-speed heterostructure devices" (2002).

He was the inaugural appointee to PMC-Sierra's in-house university, and gave courses there on "Deep sub-micron electronics" and also on "Nanoelectronics". He has given guest courses on "Modern semiconductor devices" at the Technical University of Vienna, and at the Universities of Pisa and Western Australia. He has been a Distinguished Lecturer of the IEEE Electron Devices Society, giving lectures on carbon nanotube transistors in Mexico City. Under the auspices of the Canadian International Development Agency he gave a course on "Photovotaics engineering" at the Institute of Engineering in Kathmandu.

He has published over 130 refereed articles on the topics of: electrical breakdown in thin dielectrics; the preparation and properties of plasma-anodized thin oxide films; the analysis and fabrication of surface junction solar cells; the modeling and reliability of high-gain polysilicon-emitter transistors; the analysis of silicon MIS tunnel junction structures and related devices; circuit techniques and algorithmic macrocell generation for CMOS VLSI; the compact modeling of bipolar heterostructures (supported by Nortel, Ottawa in the 1990's); the development of physical and predictive models for carbon nanotube devices, both as high-performance transistors and as biomolecular sensors.

He has spent periods of study leave at: the University of Western Australia (working on solar cells and UV photodetectors); Plessey Research, England (working on high-gain bipolar transistors); Microtel Pacific Research, Vancouver (working on CMOS memory design); Laboratoire d'Automatique et d'Analyse des Systemes, Toulouse (working on AlGaAs/GaAs HBTs); UC Santa Barbara (working on AlGaN/GaN HBTs); Technical University of Vienna (working on carbon nanotube FETs).

Research Interests

    Semiconductor device modeling, usually with the goal of producing physics-based compact models for guiding device design and evaluation.
    Presently, carbon nanotube biosensors and graphene solar cells are being studied. In the recent past, devices studied were: HBTs in the GaAs, InP and AlGaN material systems; UV photodetectors in AlGaN.

    PLEASE NOTE: My research group,
    the UBC Nanoelectronics Group , is over-subscribed, so only those students who have scholarship support, and are qualified to work on optoelectronic devices or nanoscale sensors, are encouraged to apply for research positions.
