COSOD

CENTRE FOR ORGANIC SPINTRONICS AND OPTOELECTRONICS DEVICES (COSOD)


The Centre for Organic Spintronics and Optoelectronics Devices (COSOD) was set up as an interdisciplinary research platform by Faculty of Science, Kazi Nazrul University. In our proposed Centre, we thrust for integration of research activities through interdisciplinary knowledge, training etc., which might prepare a workforce undertaking scientific challenges in innovative ways.


Field of Spintronics and Photonics, nowadays, has become a matter of intense research interest, collectively or independently, owing to the severe need of sophisticated and effective information processing. In this direction, the major thrust area of research is the development of Novel Spin-Controlled Organic Optoelectronic devices. There are several advantages of organic semiconductor over inorganic semiconductor : (a) light weight; (b) low cost; (c) mechanical flexibility and deposition over large substrate; (d) ease of production and chemical modification; (e) chemically interactive bottom-up fabricated electronics; (f) Organic based devices are more Energy Efficient and Eco friendly. Such devices can be easily integrated into various systems, such as flexible, wearable or portable electronics.


As a new and emerging University, Kazi Nazrul University has the potential of becoming a site of advanced research in this domain of sciences; and the proposed initiative is a step in that direction. We aim to set-up Foreign and National Collaboration in the proposed direction of research for effective Technology Transfer. We also aim to bring the Engineering Faculty in the contour of this Centre.
