Ferromagnetic computing (Nano-magnetoelectronics)
The present computers are based on Si technology where currents and voltages are translated into binary information. How about electron spin to do the same task? We already know devices like magnetic memory (MRAM) and magnetic storage, where electron spin processes binary information. If electron spins can be used for computing and transmitting binary information, the dream of the spin computer may come to reality.
My research in this field is to push the limit to bring the dream into reality. I have demonstrated that four ferromagnetic nanodots in a certain configuration are able to perform logical NAND and NOR operations. This was named as Magnetic Logic Gate (MLG). Each ferromagnetic dot in this architecture was about 100 nm in diameter, having an integration density up to 1.6 billion gates per square centimeter.
My current interest is Photovoltaic system. PV potential in Canada, PV systems in snowy area, DC system design are examples of my particular interests. Recently, in a collaborative work we have studied the potential of solar energy to be used in a community in Calgary city in Canada. In the past I studied solar radiation data for finding suitable locations in Bangladesh. I also researched on thin film coating material fabrication for solar energy absorption. A significant improvement of solar radiation was reported through that work.
My current interests include student successare, health and safety education for engineering students, science and engineering outreach for K-12 students, and community involvement,
