Organic Electronics group is working on fabrication of highly efficient organic field-effect transistors (OFETs) and different sensors based on OFETs. The group has fabricated few highly efficient devices with exceptional ambient stability. Such devices showed tremendous promises to be used for flexible and stretchable applications. Few devices have been demonstrated for highly sensitive gas sensors with fastest responses. The group is currently working on fabrication of OFETs for flexible and stretchable applications. We are also interested in bio-medical application of OFETs.
I addition, group is involved in understanding the basic physics at surfaces and the interfaces of different organic layers used on the devices.
We are open for active collaborations with other groups interested in working in the fields of synthesis of active materials with different functionality.
