DESCRIPTION:Prof. Andrey Turchanin\, Institute of Physical Chemistry - Fri
 edrich Schiller University Jena - Germany\nElectron irradiation of aromati
 c self-assembled monolayers results in their conversion into a novel 2D ca
 rbon material - Carbon Nanomembranes (CNMs) - molecular nanosheets with a 
 thickness of ~ 1 nm [1]. Similar to graphene or other atomically thin 2D m
 aterials (hBN\, MoS2\, etc.) CNMs possess mechanical integrity and therefo
 re can be transferred from their original substrates onto new substrates\,
  fabricated as suspended sheets or stacked into van der Waals heterostruct
 ures with the precise control over their thickness. Their physical and che
 mical properties can be tuned via an appropriate choice of molecular precu
 rsors or their post modification\, providing a flexible platform for engin
 eering of functional 2D materials. In this talk\, some examples of these m
 aterials and their device applications will be presented.\n\nThese example
 s include:\n(i) biofunctional and photoactive CNMs [2]\;\n(ii) growth of g
 raphene with adjusted electronic and structural properties [3-4]\;\n(iii) 
 chemical functionalization of graphene and MoS2 field-effect devices [5]\;
 \n(iv) nanolithography of free-standing atomically thin sheets [6]\;\n(v) 
 novel hybrid 0D/2D layered materials [7].\n\n[1] A. Turchanin and A. Gölz

 a professor of physical chemistry at the Friedrich Schiller University Jen
 a since December 2014\, where he is leading the group of “Applied Physic
 al Chemistry & Molecular Nanotechnology”. He studied physics and materia
 ls science at the National University of Science and Technology\, Moscow (
 Ph.D. 1999). In 2000 he moved to the University of Karlsruhe with an Alexa
 nder von Humboldt Fellowship. 2004-2014 he joined the Faculty of Physics a
 t the University of Bielefeld where he completed his habilitation in 2010.
  In 2012 Turchanin was awarded a Heisenberg Fellowship of the German Resea
 rch Foundation (DFG) and in 2013 the Bernhard-Heß-Prize of the University
  of Regensburg for his research in the field of emerging 2D materials. His
  current research interests are focused on the materials science of 2D mat
 erials and their applications in electronics\, optoelectronics and nanobio
 technology.
