Nature is chiral, thus chirality is a key concept required to understand a multitude of systems in physics, chemistry, and biology. The field of optics offers valuable tools to probe the chirality of nanosystems, including the measurement of circular dichroism, the differential interaction strength between matter and circularly polarized light with opposite helicity. Simultaneously, the use of plasmonic...
The mode hybridization between adjacent graphene nanoribbons determines the integration density of graphene‐based plasmonic devices. Here, plasmon hybridization in graphene nanostructures is demonstrated through the characterization of the coupling strength of plasmons in graphene nanoribbons as a function of charge density and inter‐ribbon spacing using Fourier transform infrared microscopy. In combination...
We fabricated inclined Au nanocup arrays by using the nanosphere lithography method combined with dichloromethane etching and investigated their optical properties. The transmittance spectra of these Au nanocup arrays under different polarizations and incident angles were detected and discussed. Surface plasmon resonance was employed to explain the peaks in the spectra. These inclined Au nanocup arrays...
