ECE Seminar: Anna Baldycheva Tuesday, January, 23, 2018 Anna Baldycheva Assistant Professor University of Exeter Photonics Center, 8 Saint Mary's Street, Room 339 Refreshments will be available at 10:45am outside of PHO 339 Title: Graphene and 2D Materials for Next Generation Opto-Electronicsand Photonics Abstract: Graphene is anemerging material for electronics, photonics and optoelectronics due to uniquephysical properties such as high electrical conductivity, optical transparencyand mechanical flexibility. These properties can be further enhanced ortailored to fit specific device functionalities by means of chemicalfunctionalization. A recent example of the potential of chemicalfunctionalization is the intercalation of few-layer-graphene with FeCl3(dubbed GraphExeter), which is currently the best performing carbon-basedtransparent conductor, with resilience to extreme conditions and potential fortransparent photo-detectors, flexible photovoltaic and organic light emittingdevices and foldable light-emitting devices. Among other emergingoptoelectronic materials, fluid-dispersed atomically thin 2D nanocompositematerials demonstrate great promise for the next generation of multi-functionaloptoelectronic systems with a wide range of important applications, such asrenewable energy, optical communications, bio-chemical sensing, and securityand defence technologies. In this talk, I will review our latest developments in the use of graphene and functionalized graphene for electronics, photonics and optoelectronics. I will present ourrecent studies on the use of high quality graphene for next generation lightemitting devices and for flexible, wearable touch-sensors. I will review ourrecent demonstration of 2D heterostructures for video-frame-rate imaging applications, intelligent design of 2D devices and GraphExeter photodetectors for high-definition sensing and video technologies. I will also presentour 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 2Dmaterial based 3D meta-architectures.
