Elucidating NaKSb band structure: near-band-gap photoemission spectroscopy and DFT calculations
S. A. Rozhkov, V. V. Bakin, S. V. Eremeev +7
The electronic band structure of NaKSb was studied by a combination of low-energy photoemission spectroscopy and density functional theory (DFT) calculations. The optical and…
Revealing the (111) surface electronic structure of epitaxially grown NaKSb photocathode
N. Yu. Solovova, V. A. Golyashov, S. V. Eremeev +5
A recent study has established the NaKSb(Cs) photocathode as a highly efficient emitter of spin-polarized electrons. However, the electronic structure of alkali antimonides rem…
Subthermal Mean Transverse Energies Induced by Electron Refraction on the Jump in Mass at the Surface of Multialkali Photocathodes
S. A. Rozhkov, V. V. Bakin, H. E. Scheibler +6
The search for photocathode materials with low mean transverse energies (MTEs) and, hence, low intrinsic emittance is of crucial importance for various fields of particle and solid…
Direct spin imaging detector based on freestanding magnetic nanomembranes with electron optical amplification
O. E. Tereshchenko, V. V. Bakin, S. A. Stepanov +7
An analog of the optical polarizer/analyzer for electrons, a spin filter based on freestanding ferromagnetic (FM) nanomembrane covering the entrance of the microchannel plate (MCP)…
