Speaker | Thomas Mueller received his M.S. and Ph.D. degrees in Electrical Engineering from TU Vienna in 2001 and 2004, respectively. In 2007 he joined the IBM Watson Research Center, USA, as a Postdoc, working on carbon-based optoelectronics. At the end of 2009 he returned to TU Vienna, where he currently holds an Associate Professor position. His research focuses on electronic and optoelectronic devices based on two-dimensional materials. He (co-)authored more than 90 peer-reviewed publications in leading scientific journals. Selected awards include the START-Prize, the Fritz Kohlrausch-Prize, and the ASciNA Award. |

Abstract: The materials that have enabled the information technology revolution over the past decades will 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 promising candidates. Graphene, a 2D structure of carbon atoms with unorthodox electronic properties, is the most prominent representative of the 2D material family. More recently, transition metal dichalcogenide (TMD) semiconductors have come into the focus of interest, as these offer properties that complement those of graphene. In this talk, I will present some of our results on the development of field-effect transistors and electronic circuits based on 2D semiconductors. Large-area MoS2growth by chemical vapor 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 optical 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 excellent material quality, combined with the advantages of 2D materials, such as flexibility, high mechanical stability and the possibility of heterogeneous integration with other platforms, could lead to new (opto-)electronic technologies.
