Open Positions in the Hybrid Devices Group

Doctoral Thesis - "Energy and charge transfer at interfaces of 2D semiconductors and conjugated organic molecules”

Scientific background: Following the discovery of graphene, the large family of 2D crystals has attracted significant attention. The fascinating properties of these materials in the monolayer regime arise due to the quantum confinement of the electronic excitations. Heterostructures made by combining atomically thin 2D semiconductor crystals with conjugated organic molecules and metal nanostructures provide a platform for creating new artificial materials for opto-electronic and photonic applications. The PhD position is embedded in a collaborative research center (CRC) which focuses on the exploration of these novel heterostructures employing a large variety of experimental and theoretical methods (https://www.physik.hu-berlin.de/de/sfb951). The center unites about 20 research groups of the Berlin/Potsdam area.
Job description: The PhD candidate will apply mostly optical spectroscopy with temporal and spatial resolution to gain a fundamental physical understanding of energy and charge transfer processes at interfaces between 2D semiconductors (MoS2, WS2 etc.) and conjugated organic molecules. Control over these transfer processes via external stimuli shall be explored in simple device architectures. Targeted applications are nanoscale photon sources and detectors. The PhD position is situated in the Hybrid Devices Group uniting physicists and chemists. The candidate will collaborate closely with other groups of the CRC employing complementary methods.   
  • MSc in Physics or Material Science
  • Experience in optical spectroscopy will be evaluated positively
  • Sound knowledge on semiconductors and/or molecular physics will be a plus
  • Good written and spoken skills in English
  • Ability to collaborate with an interdisciplinary team
  • Willingness to present results at conferences
The position is open starting from January 2020.
To apply, please send the following documents
(1) Letter of motivation
(2) CV including a list of publications or a short summary of the Master thesis
(3) Degree certificates and academic transcripts
