Electron escape probability in high-efficiency photocathodes measured by reverse-injection photovoltage
S. A. Rozhkov, V. V. Bakin, D. A. Kustov +4
The characterization of electron transfer through the emitting surface is of crucial importance for optimizing existing and developing new photocathodes. Here we propose and develo…
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…
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)…
