Infrared nanoscopy of Dirac plasmons at the graphene-SiO2 interface
Zhe Fei, Gregory O. Andreev, Wenzhong Bao +13
We report on infrared (IR) nanoscopy of 2D plasmon excitations of Dirac fermions in graphene. This is achieved by confining mid-IR radiation at the apex of a nanoscale tip: an appr…
Near-field spectroscopy of silicon dioxide thin films
Lingfeng M. Zhang, Gregory O. Andreev, Zhe Fei +6
We analyze the results of scanning near-field infrared spectroscopy performed on thin films of a-SiO2 on Si substrate. The measured near-field signal exhibits surface-phonon resona…
Observation of Selective Isotope Effect in the Ultraviolet excitation of N2: A Computational Study
B. H. Muskatel, F. Remacle, Mark. H. Thiemens +1
Isotope effects associated with gas phase N2 photolysis are used to interpret Martian atmospheric evolution, icy satellite atmospheric chemistry and meteorite isotopic anomalies fr…
