Abstract:
Graphene is an emerging material for photonics, optoelectronics and electronics due to unique physical properties such as high electrical conductivity, optical transparency and mechanical flexibility. These properties can be further enhanced or tailored to fit specific device functionalities by means of chemical functionalization. A recent example of the potential of chemical functionalization is the intercalation of few-layer-graphene with FeCl3 (dubbed GraphExeter), which is currently the best performing carbon-based transparent conductor, with resilience to extreme conditions and potential for transparent photo-detectors, flexible photovoltaic and organic light emitting devices and foldable light-emitting devices. Among other emerging optoelectronic materials, fluid-dispersed atomically thin 2D nanocomposite materials demonstrate great promise for the next generation of multi-functional optoelectronic systems with a wide range of important applications, such as renewable energy, optical communications, bio-chemical sensing, and security and defense technologies.
In this talk I will review our latest developments in the use of graphene and 2D materials for flexible (opto)electronics and CMOS photonics. I will present the use of high-quality graphene for next generation light emitting devices and for flexible, wearable touch-sensors and E-nose systems. I will demonstrate our recent studies on the development of graphene-enabled key components of the CMOS photonic integrated circuits for communications application and lab-on-chip technology. Finally, I will also present our most recent results on dynamically controlled three-dimensional self-assembly of suspended 2D liquid exfoliated nano-flakes, which provides a breakthrough route for technological realization of 2D material-based 3D meta-architectures on CMOS photonic chip.
