Development of Novel Oxynitride Semiconductors for Artificial Photosynthesis
Rapidly rising atmospheric CO2 levels urge the development of new technologies for renewable generation and efficient storage of energy. The application of well-established growth techniques like molecular beam epitaxy (MBE) to novel materials allows the tailoring of optical, electronical and structural properties towards the application as photoelectrochemical water splitting devices. The focus of this work lies on the investigation of the electrical and photo-electrical characteristics of Ga-Zn-O-N (GZNO), which are a crucial bottleneck for high solar-to-hydrogen conversion efficiencies. To date, the electronic transport mechanism in GZNO is unknown. By applying experimental methods like cryogenic photocurrent spectroscopy, Hall and Seebeck effect characterisation or photoelectrochemistry, we aim to gain insight into the movement of the charge carriers within the bulk and between semiconductor surface and electrolytes. Techniques you will be trained in: • Micro-structural characterization by scanning electron microscopy (SEM) and atomic force microscopy (AFM) • Electrical characterization by photocurrent spectroscopy, Hall and Seebeck effect • Optical characterization by photoluminescence and Raman spectroscopy • (Photo-)electrochemistry • Participation in sample fabrication, e.g., growth by MBE, lithography and clean room work • Improvement and possible development of scientific setups according to specific requirements Conditions and requirements: • Possible start date: From January-April 2020; Duration: one year, full-time • Focus on condensed matter physics, applied and engineering physics or related fields • Prior experience with semiconductor physics preferred, but not mandatory • Completion of all exams necessary for master’s degree • Ability to work goal-orientated and focused on a complex topic and to integrate into our team For further information, please contact To apply, please submit your transcript of records.
