TL;DR: In this article, the growth of multi-alkali K2CsSb cathodes on [100] silicon substrates measured using in situ x-ray scattering is described. And the relationship between cathode structure, growth parameters and the resulting quantum efficiency is explored.
Abstract: Alkali antimonide photocathodes have high quantum efficiency and low emittance when illuminated by visible light, and are thought to be well suited for use in highbrightness photoinjectors for 4th generation light sources. Here we report on the growth of multi-alkali K2CsSb cathodes on [100] silicon substrates measured using in situ x-ray scattering. Correlations between cathode structure, growth parameters and the resulting quantum efficiency (QE) are also explored. The best cathodes in this study have a QE at 532 nm in excess of 6% and are structurally textured K2CsSb with grain sizes in excess of 20 nm. In an attempt to reduce the complexity of the current growth methodology, we are also making alkali antimonides in parallel via the reaction of bulk materials in an inert environment. This approach has the advantage that the desired stoichiometry can be obtained exactly. Initial diffraction results from prepared bulk materials are promising and show the formation of well reacted K3Sb. In the future, we intend to transfer this material to smooth thin photocathode films by either sputtering or pulsed laser deposition.

TL;DR: In this article, a new class of III-V quasi-binary semiconductor alloys [AIIIBV]1−x[CIIIDV]x has been synthesized and bulk crystals grown from the melt for the first time.
Abstract: In this paper, the bulk growth of crack-free GaInSb and single phase GaInAsSb alloys are presented. A new class of III-V quasi-binary semiconductor alloys [AIIIBV]1−x[CIIIDV]x has been synthesized and bulk crystals grown from the melt for the first time. The present investigation is focused on the quasi-binary alloy (GaSb)1−x(InAs)x (0

TL;DR: In this article, a Fourier-optical 4f spatial frequency filter set-up as a transverse mode selector (TMS) was used for a broad area laser design with mid-infrared emission wavelength around 2 μm.
Abstract: Antimonide broad area lasers (BAL) have been prepared that include a Fourier-optical 4f spatial frequency filter set-up as a transverse mode selector (TMS). The resonator is folded about the Fourier-transform mirror with its focal length f equal to the resonator branch length d (i. e. half resonator length). The resonator length 2d is 1.65 mm and the whole resonator is gain section as well as part of the TMS. The approach to integrate BAL and TMS monolithically is verified; the experiments are typically performed around 85 K temperature. The concept can be employed for any edge emitting BAL, but we used an AlGaInAsSb-based laser design with mid-infrared emission wavelength around 2 μm, where lasers with higher output powers within the fundamental transverse mode are still needed for many applications. Above a certain operating temperature (≈140 K) a double-hysteresis emerges in the output-power versus pump-current characteristics. This as well as the free spectral range strongly suggest that both resonator branches act together as one entity.
