Balandin, Lake and Mulchandani Receive Multi-PI NSF Award for Engineering the Thermal Properties of Graphene

July 29, 2013

National Science Foundation (NSF) funded cooperating research of three BCoE researchers: Dr. Alexander A. Balandin, Professor of Electrical Engineering and Founding Chair of Materials Science and Engineering, Dr. Roger Lake, Professor of Electrical Engineering and Dr. Ashok Mulchandani, Professor of Chemical Engineering. The interdisciplinary project is entitled “Two-dimensional performance with three-dimensional capacity: Engineering the thermal properties of graphene.” Professor Balandin serves as Principal Investigator (PI) of the project responsible for materials characterization and thermal measurements. Professor Lake performs computational studies while Professor Mulchandani conducts material synthesis.

 

The unique properties of graphene – a single atomic plane of carbon atoms – were discovered in Professor Balandin’s Nano-Device Laboratory at UCR in 2008. In recent years, the attention of the research community was focused on the properties of twisted bilayer graphene – a special form of graphene bilayers where atomic planes are rotated against each other by some angle. The objective of this multi-PI NSF program is to investigate the effect of rotation angle on the thermal conductivity of twisted bilayer graphene. The all-UCR team will study a possibility of suppressing the phonon coupling in twisted graphene layers thus allowing for transfer of extraordinary large heat fluxes. The phonons are quanta of crystal lattice vibrations that carry heat in graphene.

 

The possibility of maintaining two-dimensional (2D) properties of graphene in bulk materials through the use of twisting the stacking angles is a transformational concept giving us the best of both worlds – the enhanced performance of 2D combined with the capacity of three-dimensional (3D) systems. The research is expected to lead to new breakthrough approaches for removal of heat from advanced electronic and optoelectronic devices.
