WELCOME TO NANOSCIENCE AND QUANTUM ENGINEERING RESEARCH LABORATORY
Our research involves growth, fabrication, modeling, and characterization of quantum and nano to microscale structures and devices.
Three-Dimensional Thin-film Thermoelectric Generators For Implantable and Wearable Applications
Thermoelectric generators can convert body heat to electrical energy providing a continuous source of energy for low power electronics. Small and lightweight thermoelectric generators can be integrated into wearable devices making battery-less devices a reality....
Emerging Quantum Materials
Perhaps the most vibrant areas across the landscape of physics research today lie here in the study of “Quantum Materials”. They are to be the steppingstone toward quantum computing and the frontier of new and exciting physics. But what are the quantum materials and...
Multi-phase Nanocrystalline Thermoelectric Materials
In a multi component nanocrystalline material, crystallites and interfacial nanostructures form a disordered morphology. In such a disordered nanostructured material, the energy disruption for both electrons and phonons can happen in a time scale that is smaller or...
Theory of nanoscale charge and energy transport
Coherent Potential Approximation (CPA) There is currently no quantum mechanical transport model for charge (or phonon) transport in multiphase nanocrystalline structures. Due to absence of periodicity, one cannot apply any of the elegant theorems, such as Bloch's...
Solar hydrogen fuel
The market for hydrogen is vast consisting of recent demand for renewable energies and industrial and chemical processes needs such as methanol production, ammonia (NH3), removing sulfur from gasoline, float glass production, edible fat hydrogenation, weather...
Optical characterizations and time resolved spectroscopy
Ultrafast laser pump-and-probe experiments can be used to probe carrier dynamics in electronic materials. The transient reflectivity and/or transmission measurement is an important application of the mode locked laser. Such lasers have been used to determine the...
