About Us

Welcome to Dr Tawfique Hasan's research group at the Cambridge Graphene Centre (CGC). As a team, we try to understand underlying fundamental phenomena to engineer nanomaterials for printed photonics, (opto)electronics, sensing and energy.

Our work encompasses Engineering, Physics, Chemistry, Materials Science and Nanotechnology and interfaces between industry and academia with fundamental and applied research. We employ creative synthesis, processing and deposition of functional 2 dimensional (2d) materials. By combining them with other 0d and 1d nanomaterials such as nanotubes, nanowires and metal oxides, we work towards the development of a "nanomaterial-enabled" flexible and printable device platform, with batch to batch manufacturability with photonics, optoelectronics, sensing, interfacing and energy harvesting capability. 'Hybrid materials engineering', focusing functional nanomaterials is therefore the core theme of our ambitious multidisciplinary research, with a view towards real world application development.

Want to work with us? We are always looking for highly motivated PhD students with a Chemistry, Physics, Nano-biotechnology, Materials Science or Engineering background. International post doctoral researchers for medium and long term collaborative research visits are also welcome. Please have a closer look at what we do and with a specific work program in mind, get in touch with Tawfique directly.

Production

For the majority of applications, production methods of 2-dimensional (2d) materials must be scalable without compromising the material functionalities and cost. We approach the problem by processing the 2d materials in liquid environment. More >>

Processing

Production of functional 2d materials in a liquid environment allows the choice of solvent, dispersant and incorporation of other nanomaterials. This enables us to formulate printable inks, retaining the unique functionalities of the nanomaterials. More >>

Applications

We investigate how our functional ink and printing technology can be applied to fabricate components for electronics (such as interconnects, touch surface) or optoelectronic (such as flexible devices capable of detecting light). More >>
