Optical generation rate
WebThe recombination rates of majority carriers equals that of minority carriers, because a recombination process involves an equal number of holes and electrons. ... The generation lifetime in a space charge region where the hole and electron concentration are close to each other can be derived from the SRH recombination generation equation (3. 20) WebBoth, the recombination and the generation processes are two-step processes. The sequential occurrence of sub-processes 1 and 2 leads to recombination of anelectron-hole pair. The excess energy of …

WebSuch fibers also enable pulse compression, supercontinuum generation, and optical processing [15,16]. ... In fact, the proposed fiber configuration is also applicable for the generation of high-repetition rate soliton-like pulse (SLP) trains of high peak power from weakly modulated CW radiation. To achieve the effect, the cascaded fiber ... WebHowever, the solar-to-water generation rate inside an enclosed system is usually lower than the solar-to-vapor evaporation rate in an open system due to the lower mass transfer rate. In this work, we demonstrate high rate solar distillation based on a three-dimensional copper foam (CF) cube, which offers five surfaces for absorbing direct and ...
