Nanowires and graphene are coupled to silicon waveguides to control the light polarization.  2nd European Quantum Technologies Virtual Conference EQTC 2021 ( poster ).

Graphene nano-sheets are produced by means of electrochemical exfoliation of graphite. Anodic oxidation allows high-yield production of graphene oxide in either acid or salt solutions, with the key role played by ions driven in between the graphene sheets. Faraday Discussions 227, 291 (2021).

Topological quantum matter is a novel class of materials which properties depend not on local symmetries but on nonlocal properties called topological invariants. The Raman spectra of PbSnSe nanometric flakes show phonons interacting with their topological electrons. J. Raman Spectrosc. 51, 2489 (2020).
