As is the case for normal incidence, the diffusion theory model, when shifted by Δx, also agrees with Monte Carlo results outside of 1 2 mfp' from the center of diffuse reflectance, which, it is important to reiterate, is no longer at the point of entry as shown in Ref.[ 28].
Some experimental results from the literature are difficult to explain by the existing diffusion theories using a concentration gradient or a swelling rate.
In the case of an infinite medium, the detected light intensity with a source-detector separation of r can be simply described by the diffusion approximation theory: ρ (r, t ) = c ' 4 π (1 4 π D c ' t ) 3 / 2 exp (− μ a c ' t − r 2 4 D c ' t ).
In this work, we construct a kind of type-II coaxial perovskite nanowire (ZnO/CH3NH3PbI3) and intensively investigate the nonuniformity of CSE, light absorption, and external quantum efficiency (EQE) inside the nanowires by combining the semiconductor diffusion theory and finite-difference time-domain (FDTD) simulations [22 25].
We use historical water-level records observed at hourly intervals from the University of Hawaii Sea Level Center (UHSLC) to analyze the intensity of storm surges by applying the information diffusion theory.
In conclusion, we deeply investigate the nonuniformity of the CSE, the light absorption, and the EQEs at different positions inside type-II ZnO/CH3NH3PbI3 nanowires, and their influence on PCEs of nanowire solar cells by combining the semiconductor diffusion theory and FDTD simulations.
Neutron motion in the moderator is described by diffusion theory and that in the void by the free streaming Boltzmann transport equation.
The validity of the "transfer diffusion theory" developed by Ruff and Friedrich is examined by measuring the conductivity of N, N-dimethylformamide solutions containing anthracene and its anion which undergo rapid electron exchange.
The solar diurnal variation of cosmic rays was considered to be fully explained by the diffusion-convection theory.
The modulation of galactic cosmic rays in the heliomagnetosphere (HMS) has been considered to be described by the diffusion-convection theory first proposed by Parker (1958) and theoretically formulated by Gleeson and Axford (1967).
