Contents of research
  • Development of defect mechanics-based multiscale computational models and simulation method: Safety and reliability are the major issues for high-performance electronic devices working in harsh environmental conditions. Since these devices are fabricated on a foreign substrate, defects such as dislocations and cracks are formed in the thin film because of high lattice and thermal mismatch between the film and the substrate. Such defects can become a major issue for reliability of these devices. Therefore, we are carrying out research on the mechanics of defect generation in electronic devices using multiscale simulation techniques. The studies will enble understanding of defect generation mechanisms which can help in improving the reliability of electronic devices in harsh working environments.
  • Mechanics analysis for strain engineering of nanoelectronic Devices: Quantum dot (QD) nanostructures have been used as stable light sources. However, since the QDs are manufactured from different materials with different lattice and physical dimensions, the assembled QD nanostructures can induce mechanical strains in the heterostructure. This leads to a shift of the conduction subband energy in quantum dot device. In this research, we have developed the analytical model thereby predicting the band structure useful in designing functional improvement by optimizing the electronic architecture.

Result & Expected effect
  • To develop better understanding of structural and electronic materials behavior at different length scales.
