A new paradigm of THz-energy harvester based on graphene

Future-shaping concepts such as wearable electronics and the Internet of Things are driving the quest for low-power electronics and for energy harvesting at the device or at chip level. Researchers from AMO GmbH, RWTH Aachen University, Chalmers University and the University of Wuppertal have now developed a novel type of flexible energy harvester, which shows good prospects for powering wearable and conformal devices.

A clever way of protecting graphene

One thing that has become clear in the last decade of graphene research is that it is necessary to protect the surface of graphene from external contaminants, to preserve its exceptional electronic properties and be able to exploit them into novel devices. The depositions of dielectric materials on top of graphene is therefore an essential step of manufacturing graphene-based electronic and photonic devices. [read more »]

Combining high responsivity and low power consumption in graphene-based photodetectors

Researchers from AMO GmbH, ICFO- Institut de Ciencies Fotoniques, RWTH Aachen University, and Bergishe Universität Wuppertal have developed a novel approach for graphene-based photodetectors that allows combining high responsivity and low power consumption, thus circumventing one of the major limitations of state-of-the-art photodetectors based on graphene – namely the high power-consumption caused by their large dark currents.
