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…
