Prof Monica Craciun joined the University of Exeter in January 2010 as research fellow and took up the position of Associate Professor in Nanoscience in December 2014. She currently holds a 5-year EPSRC early career fellowship (Engineering Fellowships for Growth in Advanced Materials) and is/was investigator on more than 30 EPSRC, Royal Society, Innovate UK, EU and industrial research grants with a total funding of over £9.25million. At Exeter she is full-time staff of the Centre for Graphene Science and of the Functional Materials Research Group. Prof Craciun gained a PhD in Applied Physics from Delft University of Technology (The Netherlands), an MSc in Materials Physics (Joseph Fourier University, Grenobe, France), an MSc in Applied Physics (University of Bucharest, Romania) and an MSc in Materials Engineering (Catholic University Leuven, Belgium). Before joining Exeter she was postdoctoral researcher at the University of Twente (The Netherlands) and at the University of Tokyo were she was awarded a prestigious fellowship of the Japanese Society for the Promotion of Science.

Her expertise lies in the studies of two dimensional materials (such as graphene, functionalized graphene and layered dichalcogenides) and of organic materials, as well as their use in future emerging electronic and optoelectronic applications. Currently she leads a group of 30 researchers focusing on emerging technologies such as highly efficient solar cells and light emitting devices, electronic textiles, smart windows and multifunctional smart coatings. She has a strong track record of interdisciplinary research with output in the fields of nanoscience and nanotechnology, materials science, physics and chemistry. Her research is regularly published in leading and high-impact peer reviewed journals such as Nature Nanotechnology, Advanced Materials, Nano Letters, Journal of the American Chemical Society, Proceedings of the National Academy of Sciences of USA (PNAS), Physical Review Letters, Nano Today, etc.. She has published over 70 papers, which have attracted more than 2100 citations and she has an h-index of 22.

The work of Prof Craciun spans from fundamental research in nanoscience (molecular electronics, quantum phenomena, nano electronics, spintronics) to applied research in electronic and optoelectronic materials and devices.

Molecular Electronics. Highlights of her research includes the discovery of a correlation between the electrical conduction of metal-phthalocyanine (MPc) materials and the molecular structure of their constituent molecules [J. Am. Chem. Soc. 127, 12210 (2005)] and the realisation of the first MPc ambipolar transistor [Appl. Phys. Lett. 86, 262109 (2005)]. This was followed by the first demonstration of high electrical conductivity in alkali-doped MPc [Adv. Mater. 18, 320 (2006)], which has opened up the field of metallic MPc. She also published the first experimental observation of an insulating state in pentacene induced by strong interactions between the conduction electrons [Phys. Rev. B 79, 125116 (2009)].

Quantum Phenomena & Nano electronics. Main contributions include the first experimental demonstration of charge carriers propagation in monolayer graphene via evanescent waves [Phys. Rev. Lett. 100, 196802 (2008)] and the discovery that ABA-stacked trilayer graphene is the only gate-tuneable semimetal [Nature Nanotech. 4, 383 (2009)], opening the research area of few-layer graphene (FLG). In the area of FLG she also published the first experimental evidence that trilayer graphene has a unique stacking-dependent quantum Hall effect [Phys. Rev. B(R) 84, 161408 (2011)], the first studies of electrical transport in FLG with record high charge densities controlled by liquid ionic gating [PNAS 108, 13002 (2011)], and the first direct observation of the electric field tuneable energy gap in ABC-stacked trilayer graphene [Nano Lett 15, 4429 (2015)]. The latest advance is the demonstration of a high-efficiency graphene Cooper pair splitter device [Nature Scientific Reports 2016], an essential ingredient for quantum information processing.

Electronic and optoelectronic materials and devices. These are new research directions which she has pioneered at Exeter and include novel techniques to pattern electrical circuits in Fluorine- functionalised graphene, of use for whole-graphene electronics [Nano Lett. 11, 3912 (2011)], a method to tailor the band gap of fluorinated graphene by tuning the Fluorine coverage [Nanoscale Res. Lett. 6, 526, (2011) & New J. Phys. 15, 033024 (2013)]. She discovered the GraphExeter material (i.e. few-layer graphene intercalated with FeCl3), which is currently the best performing carbon-based transparent conductor [Adv. Mater. 24, 2844 (2012)], with resilience to extreme conditions [Nature Scientific Reports 5, 7609 (2015)], extensively reported by media such as BBC, Forbes and Reuters. Furthermore, her team demonstrated the potential of GraphExeter for flexible electronics [Nature Scientific Reports 5, 16464 (2015)], transparent photo-detectors [ACS Nano 7, 5052 (2013)], foldable light emitting devices [ACS Appl Mater Interfaces 8, 16541 (2016)], used GraphExeter to provide the first evidence for magnetic ordering in the extreme limit of two-dimensional systems [Nano Lett 14, 1755 (2014)] and developed novel ways to strain graphene [Nano Lett. 14, 1158 (2014) & Nano Lett. 15, 7943 (2015)]. Her latest advances are the development of a new growth method for graphene which is 100 times faster and 99% lower cost than standard Chemical Vapor Deposition [Adv. Mater. 27, 4200 (2015)], and the creation of graphene-based electronic textiles [Nature Scientific Reports 5, 9866 (2015)].
