Dr. Samarendra P. Singh received his Ph.D. (Physics) from Indian Institute of Technology Kanpur (IITK) in 2007. He joined Institute of Materials Research and Engineering (IMRE) Singapore in 2005. After working there as a research scientist for more than six years, he joined Shiv Nadar University (SNU) in 2011 as an Assistant Professor in the department of physics.
As a physics teacher, he aims to develop a strong understanding of physical concepts among his students and inspire them to apply it to the real-world context, solving problems using analytical skills, and clear expressions with arguments in presentations. Teaching Physics is at the core of his academic career and he has worked to develop an undergraduate (UG) and postgraduate (PG) curriculum at the department of physics, SNU. The unifying theme of his research is to explore and apply novel materials involving organic semiconductors and organic-inorganic hybrid materials for device applications in field-effect transistors, solar cells, light emitting diodes, lasers, and sensors. He endeavors to enrich the understanding of Physics of carbon-based molecular semiconductors with an aim to study charge transport and photophysics of organic semiconductors. He has published over 40 research papers in international journals, 15 patents, and supervised several undergraduate and Ph.D. students. One of his patent (US patent # US8624232) got licensed by Corning Inc., USA.
Teaching Interest:
As a physics teacher, I aim to develop a strong understanding of physical concepts among my students and inspire them to apply it to the real-world context, solving problems using analytical skills and clear expressions with arguments in presentations. Teaching Physics is at the core of my academic career and I have worked to develop an undergraduate (UG) and postgraduate (PG) curriculum at Department of Physics, Shiv Nadar University (SNU). Over the last six years, I have taught courses on Classical mechanics, Electrodynamics, Thermal Physics, Waves and oscillations, Analog and digital electronics, Condensed matter physics, Physics of semiconductor materials and devices, Characterization of materials, Physics of Photovoltaic devices and Energy for a sustainable development. Since Physics teaching laboratories are an integral part of physics education, I have worked to design and develop General physics, Advanced Physics, Electronics and Computational physics teaching laboratories at SNU.
Research Interest:
I have been working in the area of organic semiconductors for more than a decade now. My research expertise broadly lies in processing and characterization of organic semiconductors, fabrication, and characterization of organic and organic-inorganic hybrid devices. The unifying theme of my research is to explore and apply novel materials involving organic semiconductors and organic-inorganic hybrid materials for device applications in field-effect transistors, solar cells, light emitting diodes, lasers, and sensors. He endeavors to enrich the understanding of Physics of carbon-based molecular semiconductors with an aim to study charge transport and photophysics of organic semiconductors. At SNU, my research group is engaged in fabrication, characterization, and investigation of device physics of organic solar cells (in conventional and inverted architecture), organic light emitting diodes and thin-film transistors. I have contributed actively to develop world-class research capabilities for research at SNU in the area of materials science and physics. Using the experimental capabilities developed at SNU, an organic solar cell efficiency of ~9.3% has already been achieved.
