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…

Optical probe of strong correlations in LaNiO thin films
M. K. Stewart, Jian Liu, R. K. Smith +5
The optical properties of LaNiO thin films are investigated over a wide energy and temperature range. Thin films of varying thickness were epitaxially grown by pulsed laser dep…
