Description
- Abstract:
- Chirality is omnipresent in nature, life, and the field of physics. One intriguing example is the homochirality of molecules, which has remained a great secret of life. Pairs of chiral molecules, known as enantiomers, are identical in atomic composition and therefore indistinguishable in their scalar physical properties. Molecular chirality does, however, reveal itself through interactions with surroundings of broken mirror-symmetry. This thesis reports on a system for molecular chirality detection, in which the mirror symmetry is doubly broken, first by asymmetric structuring of a nanopatterned plasmonic surface, then by incidence of circularly polarized light. The reported findings are the first to support the feasibility for electrically-based enantiomeric detection via optical rectification in a metal meta-grating. This technology is advantageous over other detection methods due to its size, cost, ease of use, and integration ability with read-out electronic circuits for data processing and interpretation.
