Hole Transfer Dynamics in Thin Films of Mixed‐Dimensional Quasi‐2D Perovskites
Advanced Functional Materials, EarlyView.Charge transfer dynamics in quasi‐2D perovskite (PEA2MAn−1PbnI3n+1), grown with a distinct dimensionality gradient are investigated. Selective excitation of the n = 4 phase reveals efficient hole transfer to n = 2 and n = 3 within tens of picoseconds, while n = 1 acts as a hole‐blocking layer. These findings highlight the importance of minimizing n = 1

Coupled-mode theory for resonant gratings with a varying period
Компьютерная оптика, 2023 We propose a coupled-mode theory for resonant diffraction gratings with a varying period. We consider diffractive structures, in which the reciprocal lattice vector, a quantity inversely proportional to the period, varies linearly in the direction of ...
