Interested Research Fields:

My current research interests are design and fabrication of semiconductor devices, especially non-porous and porous Si- and III-V semiconductor devices. Moreover, I am working on transparent conductors as opto-electronic devices and my students have done research on different detectors and transistors with various semiconductor materials under my supervision. In addition I have done some VLSI design and technology in my lab. During the last years I supervised several PhD, MSc and BSc projects in different areas of Microelectronics. Some of the projects supervised are as follow:
1. Porous-Si and GaAs Gas Sensors. For this research we have obtained excellent results, some of them have been published in refereed journals and conferences during 2004 and 2005.
2. MOS-MES Gas Sensors. This is an interesting research area from which we obtained excellent results and these will be published soon.
During the last few years I supervised 25 MSc projects with following titles. All of them have been finished with high marks of A and A*.
1. A Model for polycrystalline Silicon thin film transistors applicable in LCDs
2. Fabrication of Schottky gas sensors with high sensitivity and selectivity
3. Design and fabrication of Au/GaAs and ITO/GaAs Schottky diodes: Opto-electronic characterizations
4. Characterization of radiation damage in ITO/GaAs Schottky contacts

Courses:

I have taught several Post-graduate and under graduate courses during my employing at K.N.Toosi University of Technology. I have usually used new methods for lecturing especially when I intended to teach new courses in some of the semesters. For the courses taught I usually used different labs to make the students familiar with experiments and made always a relation between theory and technology. For some of the courses I have written course materials and distributed to the students. To do a good self-assessment I usually use the student survey obtained by the university to improve my methods of lecturing. The courses taught during the past years are as follow:
A ) Courses taught for post graduate students:
1) Optical Electronics
2) Semiconductor Sensors
3) Solid State Electronic Devices
4) Semiconductor Devices I
5) Semiconductor Devices II
6) Transparent Conductors
7) Theory and Technology of Semiconductor Device Fabrication
B ) Courses taught for under graduate students:
1) VLSI Design and Technology
2) Modern Physics
3) Solid State Electronics
