Terahertz tuning of Dirac plasmons in BiSe Topological Insulator
Paola Di Pietro, Nidhi Adhlakha, Federica Piccirilli +7
Light can be strongly confined in sub-wavelength spatial regions through the interaction with plasmons, the collective electronic modes appearing in metals and semiconductors. This…
