Multiphoton Photoemission Microscopy of High-Order Plasmonic Resonances at the Ag/Vacuum and Ag/Si Interfaces of Epitaxial Silver Nanowires

Abstract: Understanding the physics of surface plasmons and related phenomena requires knowledge of the spatial, temporal, and spectral distributions of the total electromagnetic field excited within nanostructures and their interfaces, which reflects the electromagnetic mode excitation, confinement, propagation, and damping. We present a microscopic and spectroscopic study of the plasmonic response in single-crystalline Ag wires grown in situ on Si(001) substrates. Excitation of the plasmonic modes with broadly tunable… Show more

“…Imaging the heterojunction by steady-state PEEM. To investigate the carrier dynamics of the coplanar 1 T′/2H-MoTe 2 heterojunction, we employed the low-energy electron microscopy (LEEM)/PEEM (Elmitec GmbH) system equipped with an energy analyzer and pump-probe technique (details in "Methods" section) 22,[32][33][34][35][36][37] , as shown in Fig. 1a.…”

“…In contrast, the time-resolved photoemission electron microscopy (TR-PEEM) method can simultaneously access the evolution of electrons on the time, space, and energy, providing a direct way to image the electrons' behavior at the nanoscale. Recently, the TR-PEEM technique has been applied to image the dynamics of surface plasmon [14][15][16][17][18][19][20][21][22][23] , the transport and recombination of carriers in bulk [24][25][26][27] , atomically thin semiconductors [28][29][30][31] , and vertical type-II semiconductor heterostructure 29 . Lateral modulation of electronic and optical properties of the in-plane structures is necessary for planar devices with high-density integration potentials in modern electronics 10 .…”

“…In this chapter, I will describe the field distribution of SPPs launched from quasi-1D Ag nanowires grown on Si(100) substrate. [37,38,73] In addition, I will go beyond the 1D coupling structure, and discuss how SPPs are launched from 2D Ag islands grown on Si(111) substrate, by imaging its 2D field SPPs interference pattern distribution. [30,31,35] The 2D fields are more complicated than the 1D case, which is due to the interference of multiple quasi-1D SPP waves coupled or reflected at edges of an Ag island.…”

“…Most PEEM studies focused so far on surface plasmon polaritons (SPP) supported by metaldielectric interfaces. Topics included SPP phase and group propagation [4][5][6][7], SPP dispersion [8,9], plasmonic focusing [10,11] and switching [12], plasmonic waveguiding [13,14], and the formation of plasmonic vortices [15].…”
