Electron density of Lowest Unoccupied Molecular Obital (LUMO) for Si Quantum Dot by using Density Functional Theory calculation.
Electron density of Highest Occupied Molecular Orbital (HOMO) for Si Quantum Dot by using Density Functional Theory calculation.
DNA - Quantum Dot interaction.
Defect in Carbon Nano-Tube modeled using juxtapostion of distribution of forces in atomistically informed continuum field theory.
Displacement field around a point defect in a thin film. Even though the medium itself is isotropic, due to the anisotropy of defect the displacement is angle dependent.
Nanoscale self-assembled monolayer on an isotropic substrate. Ordered surface patterns are obtained by using 'Mask Directed Self-assembly'.
Stress fields of a moving screw dislocation for various velocities based on our results predicated on gauge field theory. Consistent with atomistic calcalations, it is seen that supersonic speeds are possible.
Electrical fields around a strain mismatched inclusion due to nanoscale effects for various inclusion sizes. Both the inclusion and matrix are non-piezoelectric.
Our research group at the University of Houston performs multi-disciplinary research on properties, behavior and performance of materials and systems spanning the length scales from atomistic level to the gross macroscale. Research topics range from the study of coupled mechanical-optoelectronic behavior of quantum dots to gauge field theoretical approach to defects. Some examples of ongoing research work include:
