Power-effective integral thermoelectric solar radiation converter
Вестник Дагестанского государственного технического университета: Технические науки, 2020 Aim. This article is devoted to the conversion of solar radiation into electricity using the joint effect of several methods, which complement each other by transforming the disadvantages of one method into the advantages of another method. Methods. Heat

Suppression of star formation in dwarf galaxies by grain photoelectric feedback [PDF]
, 2016 Photoelectric heating has long been recognized as the primary source of heating for the neutral interstellar medium. Simulations of spiral galaxies found some indication that photoelectric heating could suppress star formation. However, simulations that include photoelectric heating have typically found that it has little effect on the rate of star ...

Time interval and lattice vibration in Raman effect, photoelectric effect and plane mirror reflection [PDF]
Modern Physics Letters B, Vol. 26, No. 18, pp. 1250115, (2012), 2012 Time interval between the incident and scattered photon in Raman effect and absorption of photon and emission of electron in photoelectric effect has not been determined till now. This is because there is no such high level instrument discovered till now to detect time interval to such a small level. But this can be calculated theoretically by applying

Photoelectric Effect at Ultrahigh Intensities [PDF]
Physical Review Letters, 2007 In the spectral range of the extreme ultraviolet at a wavelength of 13.3 nm, we have studied the photoionization of xenon at ultrahigh intensities. For our ion mass-to-charge spectroscopy experiments, irradiance levels from 10(12) to 10(16) W cm(-2) were achieved at the new free-electron laser in Hamburg FLASH by strong beam focusing with the aid of a ...

The nuclear photoelectric effect [PDF]
Proceedings of the Royal Society of London. Series A - Mathematical and Physical Sciences, 1935 Some time ago we reported in ‘Nature’ the observation of a nuclear photo-effect, the disintegration of the deutron by γ-rays. An effect of y-rays upon complex nuclei might be expected to occur from analogy with the phenomena of excitation and ionization of atoms by light, and such an effect has been looked for from time to time by various ...

Density functional theory and non-relativistic photoelectric effects in the few-electron atomic systems [PDF]
arXiv, 2022 Closed analytical formulas are derived for the differential and total cross sections of the non-relativistic photoelectric effect in the three main classes of few-electron atomic systems: (1) neutral atoms and positively charged atomic ions which contain more than one bound electron, (2) negatively charged atomic ions, and (3) one-electron atoms and ...

Effect on Dark Matter Exclusion Limits from New Silicon Photoelectric Absorption Measurements [PDF]
Phys. Rev. D 104, 063002 (2021), 2020 Recent breakthroughs in cryogenic silicon detector technology allow for the observation of single electron-hole pairs released via particle interactions within the target material. This implies sensitivity to energy depositions as low as the smallest band gap, which is $\sim1.2$ eV for silicon, and therefore sensitivity to eV/$c^2$-scale bosonic dark ...
