TL;DR: In this paper, the authors tune the Fermi level of graphene via electrical gating with the help of ionic liquid to control the transmittance of the transceiver.

TL;DR: In this article, a liquid crystal based terahertz phase shifter with the graphene films as transparent electrodes was demonstrated, and the maximum phase shift was 10.8 degree and the saturation voltage was 5 V with a 50 µm liquid crystal cell.

TL;DR: A liquid crystal based terahertz phase shifter with the graphene films as transparent electrodes is demonstrated, providing a continuous tunability, fully electrical controllability, and low DC voltage operation.

TL;DR: This work tunes the Fermi level of graphene via electrical gating with the help of ionic liquid to control the THz transmittance, and finds that, in theTHz range, both the absorbance and reflectance of the device increase proportionately to the available density of states due to intraband transitions.

TL;DR: In this article, a hybrid structure of a graphene nanomesh with the gold nanodisks is studied to enhance the light absorption by the localized surface plasmon resonance, and the authors demonstrate the potential of constructing graphene based photodetectors with a high light absorption efficiency and wavelength selectivity.
