Webreproducibility while minimizing the parasitic scattering. Typical SAXS windows include low-Z materials such as beryllium and diamond, thin polymer films and thin sheets of mica. The scattering signal is optimized when the sample path length is approximately equal to the attenuation length, which for aqueous solutions is 1–3 mm for 8–12 ... WebJul 9, 2024 · Using nonequilibrium Green's functions, possible parasitic paths are identified in two-well scattering-assisted terahertz quantum cascade lasers operating at 3.5 THz. The majority of electrons in the upper laser state can escape through these paths, causing a 66% loss of population inversion at 50 K.
