the chlorobenzene-quenched crystallization process, which we call a molecule-extrusion process. The core coordination complex between the deprotonated phosphonic acid group of the molecule and lead polyiodide of perovskite is responsible for both mechanical absorption and electronic charge transfer, and ...

A common approach to measure stability is to use the stride map to find periodic walking motions and then determine whether small deviations to the periodic motion will lead to the system diverging away from the periodic motion or returning to it. This is done systematically by analytically or ...
In the calculation, the triple-cation perovskite was simplified by the cubic formamidinium lead halide (FAPbI3) to largely reduce the time consumption [23]. To determine the predominant source for defects within the FAPbI3, we estimated the formation energy of all sorts of defects close to ...
However, fitting decays of multilayer samples remains challenging, as an incorrect modelling of the layer stack, of the band alignment or of the boundary conditions can easily lead to data misinterpretation16,33. To overcome this issue, we chose to fit the simplest model possible, that is based...
5b, very narrow DOS distributions, such as those resulting from single polymer chains48, lead to narrower R ct curves with a reduced resistance to charge transfer (increased rate constant). Increasing σ broadens the R ct curve, shifts the minimum toward more negative energies (higher positive ...
Thomas P. Russell, the Silvio O. Conte Distinguished Professor of Polymer Science and Engineering at the University of Massachusetts in Amherst, received his Ph.D. degree in 1979 in Polymer Science and Engineering from the University of Massachusetts Amherst. He is also a visiting faculty at the...
Therefore, the ionic current of the electron battery can successfully interact with living cells to stimulate the Ca2+ wave. Moreover, during the stimulation process, the ionic current from the electron battery did not cause electrochemical reactions in the biosystem. If a traditional battery were ...
In recent scenarios, several studies have focused on the versatile molecular passivation strategy aimed at mitigating various intrinsic point defects in the HP film4,21,22. Surface or bulk areas can lead to the formation of under-coordinated Pb2+ions, A-site vacancies/interstitial defects, and ha...
