Experimental setup for low-energy laser-based angle resolved photoemission spectroscopy.
A laser-based angle resolved photoemission (ARPES) system utilizing 6 eV photons from the fourth harmonic of a mode-locked Ti:sapphire oscillator is described. This light source greatly increases the momentum resolution and photoelectron count rate, while reducing extrinsic background and surface sensitivity relative to higher energy light sources. In this review, the optical system is describe...
متن کاملA tunable low-energy photon source for high-resolution angle-resolved photoemission spectroscopy.
We describe a tunable low-energy photon source consisting of a laser-driven xenon plasma lamp coupled to a Czerny-Turner monochromator. The combined tunability, brightness, and narrow spectral bandwidth make this light source useful in laboratory-based high-resolution photoemission spectroscopy experiments. The source supplies photons with energies up to ~7 eV, delivering under typical conditio...
متن کاملFabricating a Slit Array for Laser-Based Angle-Resolved Photoemission Spectroscopy
The data obtained by the laser-based angle-resolved photoemission spectroscopy (ARPES) system in Dan Dessau’s lab depends on a small wire array inside the machine. The current model of the slit array ages with time and could be improved. One method of preventing aging of the outer layer of the slit array includes changing the fabrication process and material with which its made. This new slit a...
متن کاملAngle-resolved photoemission spectroscopy of liquid water at 29.5 eV
Angle-resolved photoemission spectroscopy of liquid water was performed using extreme ultraviolet radiation at 29.5 eV and a time-of-flight photoelectron spectrometer. SiC/Mg coated mirrors were employed to select the single-order 19th harmonic from laser high harmonics, which provided a constant photon flux for different laser polarizations. The instrument was tested by measuring photoemission...
متن کاملCuprates La2−xSrxCuO4 Studied by Angle-resolved Photoemission Spectroscopy
We have performed a systematic angle-resolved photoemission spectroscopy (ARPES) study of the high-Tc cuprates La2−xSrxCuO4, ranging from the underdoped insulator to the superconductor to the overdoped metal. We have revealed a systematic doping evolution of the band dispersions and (underlying) Fermi surfaces, pseudogap and quasi-particle features under the influence of strong electron-electro...
