Spectroscopic photoemission microscopy is a well-established method to investigate the electronic structure of surfaces. In modern photoemission microscopes, the electron optics allow imaging of the image plane, momentum plane, or dispersive plane, d

We introduce a new technique, namely time-resolved vector microscopy, that enables us to compose entire movies on a sub-femtosecond time scale and a 10 nm scale of the electric field vectors of surface plasmon skyrmions.

Nanophotonic platforms such as metasurfaces, achieving arbitrary phase profiles within ultrathin thickness, emerge as miniaturized, ultracompact and kaleidoscopic optical vortex generators. However, it is often required to segment or interleave indep

We demonstrate the broadband THz antireflection coating based on bismuth nanofilms. The antireflection effect stems from the complex-valued conductivity of bismuth, providing excellent impedance matching with high-index dielectrics such as silicon, i

When graphene is placed on a crystalline surface, the periodic structures within the layers superimpose and moire superlattices form. Small lattice rotations between the two materials in contact strongly modify the moire lattice parameter, upon which

Time-resolved imaging of the propagation and interference of isolated ultrashort surface plasmon polariton wave packets is demonstrated using two photon photoemission microscopy. The group- and phase velocity of individual wave packets are determined

We describe time resolved electron diffraction on bismuth films. Lattice heating following femtosecond laser excitation is observed via the transient Debye-Waller effect. Our results indicate different heating processes with different time constants.
