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 20 EPSRC, Royal Society, Innovate UK, EU and industrial research grants with a total funding of over £7.5M. 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 and of organic materials. 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 50 papers, which have attracted more than 1980 citations and she has an h-index of 21.

Research interests

The work of Prof Craciun spans from fundamental research in organic electronics and quantum electronics to applied research in electronic and optoelectronic materials and devices.

Early highlights of her research on graphene materials include the first experimental demonstration of propagation of charge carriers in monolayer graphene via evanescent waves [Phys. Rev. Lett. 100, 196802 (2008)] and the discovery that trilayer graphene is the only gate-tuneable semimetal [Nature Nanotech. 4, 383 (2009)], opening the research area of few-layer graphene. 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)] and the first studies of electrical transport in few-layer graphene with record high charge densities controlled by liquid ionic gating [P. Natl. Acad. Sci. USA 108, 13002 (2011)].

Notable research on graphene which Prof Craciun pioneered at Exeter includes novel techniques to pattern electrical circuits in Fluorine- functionalised graphene, of use for whole-graphene electronics [Nano Lett. 11, 3912 (2011)], and she demonstrated 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 also used her multidisciplinary expertise in material science and physics to discover the GraphExeter material (i.e few-layer graphene intercalated with FeCl3), which is currently the best graphene-based transparent conductor [Adv. Mater. 24, 2844 (2012)]. This discovery was extensively reported by national and international media organisations in 2012, such as BBC, Forbes and Reuters, and is the most downloaded article for the scientific journal Advanced Materials. Furthermore, her team showed that GraphExeter can be used effectively as electrode in transparent photo-detectors [ACS Nano 7, 5052 (2013)] and used GraphExeter to provide the first evidence for magnetic ordering in the extreme limit of two-dimensional systems [Nano Lett 14, 1755 (2014)]. She is also the leading author of a review on graphene devices [Nano Today, 6, 42 (2011)], a review on the properties and applications of functionalized graphene [J. Phys.: Condens. Matter 25, 423201 (2013)] and co-authored a book on graphene [“Graphene - Synthesis, Characterization, Properties and Applications”, ISBN: 978-953-307-292-0].

Highlights of Dr Craciun's research in the field of organic electronics 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)].
