Porous carbon films, attributed to their superior thermal and chemical robustness, are attractive for a number of applications. In the context molecular separation, major focus has been on films where effective pore diameter is lower than 1 nm, e.g., sieves. Only handful reports available hosting 2–3 nm size channels gas transport mainly takes place by Knudsen diffusion in contrast activated tr...

With attention to the thin film structure of colloidal quantum dot solar cells, in this paper in order to improvement of active layer absorption of them, we have proposed the use of nanostructure pattern for enhancement of their performance. For this purpose we have presented suitable nano hemisphare patterns in colloidal quantum dot solar cells for light trapping in absorption layer. Then with...

where q is the wave vector and rj represents the spatial coordinates of the j-th center of mass in the pattern. The forward scattering (q = 0) is omitted for consistency with the definition of the ensemble-average structure factor of an infinite point configuration ( ) 1 ( ) S h ρ = + q q in which ρ is the number density, ( ) h q is the Fourier transform of the total correlation function 2 ( ) ...
