Surface Characterization and Field Emission Measurements of Copper Samples inside a Scanning Electron Microscope

Vacuum breakdown in normal-conducting accelerating structures is a limiting factor for high gradient acceleration. Many aspects of the physics governing the breakdown process and its onset are yet to be fully understood. At Uppsala University we address these questions with an in-situ experimental setup mounted in an environmental scanning electron microscope. It consists of a piezo motor drive...

Field emission of metal nanowires studied by first-principles methods

We study the field-emission properties of an ultrathin silver nanowire using first-principles methods. The simulation and analysis of the field emission are carried out based on density-functional theory using a localized basis scheme. Through the explicit time evolution of wavefunctions, we obtain the emission currents and spatial distributions of emitted electrons from a silver nanowire. In c...

Direct observation of amplified spontaneous emission of surface plasmon polaritons at metal/dielectric interfaces

We report on direct observation of amplified spontaneous emission (ASE) of surface plasmon polaritons (SPPs) at the interface of a silver film and a gain medium. Based on a typical Kretschmann configuration incorporated with Rhodamine 6G molecules, the growing ASE spectra of SPPs have been clearly identified by carefully conducting a pump-dependent angle-resolved spectral measurement. Spectral ...

Near-field observation of surface plasmon polariton propagation on thin metal stripes

We use a Photon Scanning Tunneling Microscope to probe the field of surface plasmon polaritons modes excited on finite width thin metal films (metal stripes). We first investigate the coupling between surface plasmons launched by a focused beam on a homogeneous thin film and the modes sustained by metal stripes of different widths. We show that, if the width of the metal stripe is about a few m...

Surface charge compensation for a highly charged ion emission microscope.

A surface charge compensation electron flood gun has been added to the Lawrence Livermore National Laboratory (LLNL) highly charged ion (HCI) emission microscope. HCI surface interaction results in a significant charge residue being left on the surface of insulators and semiconductors. This residual charge causes undesirable aberrations in the microscope images and a reduction of the time-of-fl...
