Fig. 8.2 Schematic diagram of valley-selective light–matter coupling in chiral microcavities. Helicity is indicated by circled arrows and +/− superscript of the cavity mode C. Individual coupling to
distinct valleys (K/K’) gives rise to different spectral features: polariton energy–momentum dispersion branches (left), or Purcell regime (right). The centre box shows the simplified band structure
of a 2D membrane in an open cavity. The boxes at the side represent the excitonic picture in which
polarised cavity light interacts with matter (coupling strength indicated by arrow style and label)
netic solver [96]) and the design of the required chiral photonic structures with the
help of an evolutionary neural learning algorithm. The obtained preliminary results
with reflectance differences in the few-percent regime promise a considerable impact
on coupling situations in future light–matter interaction experiments involving optimised chiral reflectors.
8.6 Functional Nanomaterials Sciences Cooperation Group
2D-materials research is a hot topic of functional nanomaterials science. The combination of 2D and 0D systems, as well as 3D materials, delivers a measureless scope to
explore materials science and promotes the performance of electronic, optoelectronic
and thermoelectric devices. With a collaboration project dedicated to the utilisation
and understanding of various nanostructured heterojunctions or material systems, the
achievements in this area may be enhanced and a long-term network for scientific
cooperation and exchange of ideas established. Moreover, the joint research may
allow the combination of the cooperation partners’ skills to obtain new capabilities
not available in the individual groups’ environment, and train a new generation of
interdisciplinary young scientists.
Based on the interests of the cooperation group members and their key competences, the scientific objectives can be summarised as follows: (1) 2D-system photodetectors and sensors; (2) 2D- and nanomaterials light–matter coupled systems. It
shall be noted that the choice of objectives and the range of related scientific topics
