Phase change materials for nano-polaritonics: a case study of hBN/VO2 heterostructures
S. Dai, J. Zhang, Q. Ma +11
Polaritonic excitation and control in van der Waals (vdW) materials exhibit superior merits than conventional materials and thus hold new promise for exploring light matter interac…
Scattering of electromagnetic waves from a cone with conformal mapping: application to scanning near-field optical microscope
S. T. Chui, Mengkun Liu, Xinzhong Chen +2
We study the response of a conical metallic surface to an external electromagnetic (EM) field by representing the fields in basis functions containing integrable singularities at t…
Artifact Free Transient Near-Field Nanoscopy
Aaron Sternbach, James Hinton, Tetiana Slusar +11
We report on the first implementation of ultrafast near field nanoscopy carried out with the transient pseudoheterodyne detection method (Tr-pHD). This method is well suited for ef…
Relative efficiency of polariton emission in two-dimensional materials
Siyuan Dai, Qiong Ma, Yafang Yang +15
We investigated emission and propagation of polaritons in a two dimensional van der Waals material hexagonal boron nitride (hBN). Our specific emphasis in this work is on hyperboli…
Ultrafast and Nanoscale Plasmonic Phenomena in Exfoliated Graphene Revealed by Infrared Pump-Probe Nanoscopy
Martin Wagner, Zhe Fei, Alexander S. McLeod +14
Pump-probe spectroscopy is central for exploring ultrafast dynamics of fundamental excitations, collective modes and energy transfer processes. Typically carried out using conventi…
