Delay in Photoemission
Defining Time-Zero When a high-energy photon hits an atom and is absorbed, the result can be the excitation and emission of an electron. This photoemission, or photoelectric effect, is generallyExpand

Atomic transient recorder
In Bohr's model of the hydrogen atom, the electron takes about 150 attoseconds (1 as = 10-18 s) to orbit around the proton, defining the characteristic timescale for dynamics in the electronic shellExpand

Attosecond Nanoplasmonic Field Microscope
Nanoplasmonics deals with collective electronic dynamics on the surface of metal nanostructures, which arises as a result of excitations called surface plasmons. This field, which has recentlyExpand

Direct Measurement of Light Waves
The electromagnetic field of visible light performs ∼1015 oscillations per second. Although many instruments are sensitive to the amplitude and frequency (or wavelength) of these oscillations, theyExpand

Attosecond real-time observation of electron tunnelling in atoms
Atoms exposed to intense light lose one or more electrons and become ions. In strong fields, the process is predicted to occur via tunnelling through the binding potential that is suppressed by theExpand

Fabrication and characterization of EUV multilayer mirrors optimized for small spectral reflection bandwidth
Abstract.Our aim was to produce EUV multilayer mirrors with a small spectral bandwidth ΔE≤3 eV at 70 eV peak energy using UHV electron beam evaporation by varying the thickness ratio (Γ=) between theExpand
