DESCRIPTION:Thomas Mueller received his M.S. and Ph.D. degrees in Electric
 al Engineering from TU Vienna in 2001 and 2004\, respectively. In 2007 he 
 joined the IBM Watson Research Center\, USA\, as a Postdoc\, working on ca
 rbon-based optoelectronics. At the end of 2009 he returned to TU Vienna\, 
 where he currently holds an Associate Professor position. His research foc
 uses on electronic and optoelectronic devices based on two-dimensional mat
 erials. He (co-)authored more than 90 peer-reviewed publications in leadin
 g scientific journals. Selected awards include the START-Prize\, the Fritz
  Kohlrausch-Prize\, and the ASciNA Award.\nAbstract: The materials that h
 ave enabled the information technology revolution over the past decades wi
 ll soon reach their physical limits. Novel nanomaterials and technologies 
 have therefore become a major focus of current solid-state device research
 \, with two-dimensional (2D) atomic crystals being one of the most promisi
 ng candidates. Graphene\, a 2D structure of carbon atoms with unorthodox e
 lectronic properties\, is the most prominent representative of the 2D mate
 rial family. More recently\, transition metal dichalcogenide (TMD) semicon
 ductors have come into the focus of interest\, as these offer properties t
 hat complement those of graphene. In this talk\, I will present some of o
 ur results on the development of field-effect transistors and electronic c
 ircuits based on 2D semiconductors. Large-area MoS2growth by chemical vapo
 r deposition\, together with the development of 2D logic stages\, enabled 
 the realization of large-scale integrated circuits. I will then review our
  activities on photocurrent generation in graphene and applications in opt
 ical communications. The focus of our work in this sub-field is on the 2D 
 material integration into silicon chips for photonic integrated circuits. 
 Finally\, I will review our work on electrically driven light emission and
  photovoltaic energy conversion in TMDs. It is envisioned that the excelle
 nt material quality\, combined with the advantages of 2D materials\, such 
 as flexibility\, high mechanical stability and the possibility of heteroge
 neous integration with other platforms\, could lead to new (opto-)electron
 ic technologies.
