A warm welcome!
The group for optoelectronic materials and devices deals with the production and characterisation of semiconductor structures for optical and electronic applications, e.g. in quantum information technology. Quantum effects are utilised in these semiconductor structures in order to obtain novel properties. One example of this is the atomically sharp energy levels in semiconductor quantum dots.
Research
One focus of our work is the production of semiconductor heterostructures using molecular beam epitaxy (MBE), an ultra-high vacuum deposition process that enables the highest material qualities and purities. After growth, these heterostructures are characterised structurally, optically and electrically. For structural analyses, we use high-resolution X-ray diffraction, scanning and transmission electron microscopy and atomic force microscopy. Optically, the samples are analysed using photoluminescence spectroscopy, reflection measurements and spatial resolution methods. Electrical characterisation is mainly carried out using Hall measurements, capacitance-voltage spectroscopy and current-voltage measurements.
