Physicists shed light on the properties of plasmons in nanostructured graphene

A group of scientists from Russia and Austria has demonstrated that the interaction between plasmon oscillations in nanostructured graphene causes a significant shift in the far IR light absorption spectrum. Plasmons, collective excitations of electrons in solids, were demonstrated to change their properties under the influence of the electric field in low-dimensional materials, such as graphene, thus breaking new ground for a plethora of optoelectronic applications, including sensors, detectors, radiation sources and many others. The findings will enable modeling plasmon spectra and using the modeling results in optoelectronics. The results of the study were published in ACS Photonics.
