Advanced Material and Devices
Our research focuses on the development of novel materials and devices for different applications. We grow different quantum materials for applications in photonics, devices and sensing. In addition, we conduct Density Functional Theory (DFT) for basic material and device understanding of these materials for bandgap engineering and developing next generation devices.
Quantum Materials
2D semiconductors like Molybdenum disulfide (MoS2) still have issues in forming good metal electrode (Schottky and Ohmic) especially for mono layer (ML) to few layers thick due to strain and metallization issues. We have explored 2D semi-metals, such as titanium disulfide (TiS2), for making different types of contacts with ML MoS2 using density functional theory (DFT).
Organic Semiconductors
Organic mixed ionic-electronic conductors (OMIECs), which transport both ionic and electronic charges, development are important for progressing bioelectronic and energy storage devices.
