• Biography

  Dr. Muhammad Usman was graduated from the Electrical & Computer Engineering Department of Purdue University in August 2010. He is currently working as a researcher at Tyndall National Institute. His area of research is theory, modeling, and simulations of semiconductor materials, alloys, heterostructures, and optoelectronic devices. Dr. Usman has several collaborations with the renowned experimental groups at Imperial College London UK, Kobe University Japan, National Nanotechnology Lab Italy, Surrey University UK, Philipps University Marburg Germany, etc.

  Dr. Usman’s most recent work involves the electronic structure theory and optical properties of the bismuth-based III-V alloys (GaBiAs, GaBiNAs, InGaBiAs, AlGaBiAs, etc). The QW devices based on these novel alloys are expected to revolutionize the design of next generation semiconductor lasers working at the telecommunication wavelengths. This European Union (FP-7) project which is being done in collaboration with the experimental and industry partners involves establishing the first-ever tight binding models for the bismide materials and the subsequent derivations of the 12/14-band k.p models to study the electronic structure and loss/gain mechanisms in the bismide quantum well nano-structures. Further details about this project can be found at: http://www.biancho.org/

  Dr. Usman is also affiliated with NCN and nanoHub.org. He is a junior member of American Physical Society (APS), and a member of IEEE and Material Research Society (MRS).
