Sebin Devasia, PhD
Assistant Professor in Physics
Welcome to my personal research profile.
As a materials researcher, I aim to contribute to the field of materials science through my expertise and passion for research. Feel free to explore my profile to learn more about my educational background, research interests, and professional experience.
Research Interests
Delving into the realm of materials science has always been my primary research interest. My work focuses on electronic and optoelectronic materials, aiming to unravel the complexities of light-matter interactions and charge transport phenomena in semiconductors. Through my research, I aspire to make meaningful contributions to the scientific community and advance our understanding of the natural world.
To deepen my understanding of these materials, I utilize cutting-edge computational calculations based on density functional theory (DFT) to shed light on the electronic and optical properties of these materials and contribute to the advancement of their utilization in practical applications.
