My area of research is theoretical and computational nano-electronics. I am studying III-V quantum dots for optical and quantum computing applications. My research heavily depends on theory of condensed matter and large-scale high performance cluster computing. I model and simulate realistic experimental devices using Nanoelectronic modeling simulator NEMO 3-D. I am also an active participate of Network of Computational Nanotechnology (NCN) to develop Nanoelectronic tools and make them available for general community use around the globe.
The Projects that I have completed or currently working on are:
1. III-V Single and Stacked Quantum Dots
2. Strain Relaxed Quantum Dots for Optical Fiber Communication Devices
3. Ground State Optical Transition Rate Engineering (Under Work)
4. Quantum Confined Stark Effect in Single and Coupled Quantum Dots (Under Work)
In Future, I am planning to do following projects:
1. g-factor engineering in single and stacked III-V QDs 2. Anisotropic exchange splitting and Finite structure splitting in III-V QDs
