WebSep 12, 2024 · The Compton Effect. The Compton effect is the term used for an unusual result observed when X-rays are scattered on some materials. By classical theory, when an electromagnetic wave is scattered off atoms, the wavelength of the scattered radiation is expected to be the same as the wavelength of the incident radiation. WebIn this paper, the photoelectric and photoconduction properties of devices with twofold SRO films were studied. Devices with SRO10/SRO50, SRO20/SRO50 and SRO30/SRO50 (subindex indicates the Ro value) were fabricated. The SRO50 layer has the purpose of isolating the silicon bulk effects from the SRO effect.
