Research Interests
Experimental condensed matter physics and nanotechnology. My research interest is highly interdisciplinary, synthesis of single crystals layered materials, nanostructure fabrication, physics of materials and devices with nanoscale features. I am interested in studying electrical, optical and magnetic properties of two-dimensional layered semiconductors such as transition metal dichanlcogenides (TMDCs). When the thickness of these layered materials decreased to few atomic layers or even single atomic layer form, very interesting properties emerges due to quantum confinement effect. I am interested in investigating both fundamental physics as well as engineering devices for potential technological applications. My current research interest is in the following areas:

  1. 2D Layered semiconductors for Field-effect transistors (FETs) application
  2. Insulator-to-Metal transition on 2D semiconductor
  3. Photovoltaic, Phototransistors and novel optical effect on 2D semiconductor
  4. Magnetic data storage and spitronic based devices on magnetic nanostructures
