    Epitaxy provides an exciting possibility to explore the material properties at the nanoscale. At our chair, you will have the opportunity to explore a wide range of III-V material systems for optoelectronic and photonic applications. Quantum dots as 0-dimensional (0-D) structures are excellent single-photon sources, and we work to address all telecom windows for different applications. 2-Dimensional (2-D) structures provide the possibility of stacking materials, and epitaxy is the platform for their realization. Here, we address light-matter interaction in semiconductors and organic-inorganics combinations.

    With several MBE machines dedicated for Arsenides, Phosphides, and Antimonides, there are always topics available for Bachelor and Master’s Thesis. The growth-related projects can provide possibilities to work with MBE for growth and with different characterization tools for optimization. For example, some of these tools are Photoluminescence (PL), scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray diffraction (XRD), Reflectivity, etc. Few topics are listed below for different material systems: 

    1. Growth and characterization of QDs as single-photon sources
    2. Growth and characterization of Quantum Wells (QWs)
    3. Growth and characterization of Resonant tunneling diode structures

    There are always more topics available on growth and characterization of QDs, microcavities. Feel free to call and write an email for discussion.
