Nanoscale Science & Technology Research Group

Department of Electrical and Electronic Engineering, Bangladesh University of Engineering and Technology (BUET)

Nanoscale Science & Technology (NST) research group, lead by Dr. Md. Kawsar Alam [Professor, EEE, BUET], is interested in both the aspects of nanotechnology: Top-Down and Bottom-Up approaches. In one hand, we explore current commercial trends of nanoscale methods/ technologies and research on the devices compatible with existing technologies. On the other hand, We work on structures, methods and devices that are not yet available commercially, but may be the future of nanotechnology. We also work on analytical/ empirical/ semi-empirical/ compact modeling techniques of different devices to reduce huge memory and time requirement associated with numerical simulations and to improve computational efficiency as well as understanding of physical phenomena of such devices. We are equipped with in-house 1D/2D/3D device simulators, widely used open-source molecular level device simulation softwares as well as some commercial softwares through our collaborators.We also have access to standard High-Performance-Computing (HPC) facility to run our large-scale simulation works.
