Ion-mediated hopping electrode polarization model for impedance spectra of CH3NH3PbI3
(American Institute of Physics, 2020-08-18)
Methylammonium lead iodide (CH3NH3PbI3) is one of the most attractive materials for optoelectronic applications, and it is the most typical absorber in perovskite solar cells, which are unprecedentedly successful devices ...
Removing Instability-Caused Low-Frequency Features in Small Perturbation Spectra of Perovskite Solar Cells
(American Chemical Society, 2020-06-29)
Small-perturbation frequency-domain techniques such as impedance spectroscopy and intensity-modulated photocurrent spectroscopy (IMPS) have become important methods for the investigation of the physical working mechanisms ...
Complex shaping of the depth of focus
(Optical Society of America, 2020)
In this manuscript an exact solution to the inverse problem of axial beam shaping along the focus of a convergent lens is found. This allows to extend, within the framework of the scalar theory of diffraction, the mathematical ...
Broadband dielectric response of silk Fibroin/BaTiO3 composites: Influence of nanoparticle size and concentration

Combining Modulated Techniques for the Analysis of Photosensitive Devices
(Wiley-VCH GmbH, 2021-09-03)
Small-perturbation techniques such as impedance spectroscopy (IS), inten-sity-modulated photocurrent spectroscopy (IMPS), and intensity-modulated photovoltage spectroscopy (IMVS) are useful tools to characterize and model ...
A three-dimensional model to describe complete human corneal oxygenation during contact lens wear
(Wiley, 2022-10-10)
We perform a novel 3D study to quantify the corneal oxygen consumption and diffusion in each part of the cornea with different contact lens materials. The oxygen profile is calculated as a function of oxygen tension at the ...
Interfacial Mechanism for Efficient Resistive Switching in Ruddlesden-Popper Perovskites for Non-volatile Memories
(American Chemical Society, 2020-01-16)
Ion migration, one origin of current–voltage hysteresis, is the bane of halide perovskite optoelectronics. Herein, we leverage this unwelcome trait to unlock new opportunities for resistive switching using layered ...
