Unlike silver and gold, aluminum has material properties that enable strong plasmon
resonances spanning much of the visible region of the spectrum and into the ultraviolet. This …

We use subcycle time-resolved photoemission microscopy to unambiguously distinguish
optically triggered electron emission (photoemission) from effects caused purely by the …

Colloidal self‐assembly merges the flexibility provided by (wet‐chemical) colloid synthesis
and the structural diversity offered by self‐assembly. Using plasmonic nanocrystals as …

The miniaturization of optical devices is a prerequisite for broadband data-processing
technology to compete with cutting-edge nanoelectronic circuits. For these future nano …

Fabricating plasmonic nanowire waveguides and circuits by lithographic fabrication
methods is highly desired for nanophotonic circuitry applications. Here we report an …

The design of noble-metal plasmonic devices and nanocircuitry requires a fundamental
understanding and control of the interference of plasmonic modes. Here we report the first …

We report the observation of optical near fields in a photonic waveguide of conductive
indium tin oxide (ITO) using multiphoton photoemission electron microscopy (PEEM) …

We report the direct microscopic observation of optical energy transfer from guided photonic
modes in an indium tin oxide (ITO) thin film to surface plasmon polaritons (SPP) at the …

We studied the near-field properties of localized surface plasmon resonances in finite linear
gold nanochains using photoemission electron microscopy (PEEM). The localization of the …
