Polymer Network Modified Perovskite for High‐Performance Pure Blue Light‐Emitting Diodes

Advanced Functional Materials, EarlyView.
A polymer network of poly(4‐vinylphenol) (PVPh) is introduced to improve pure blue perovskite light‐emitting diodes. PVPh effectively passivates defects, enhances film morphology, reduces lattice strain, and suppresses ion migration. These effects lead to record device performance, achieving 9.82% external quantum efficiency and stable blue emission at

Grain boundary inhomogeneity and grain boundary heterodiffusion

Philosophical Magazine A, 1995
It is shown that the inhomogeneity of the grain boundary (GB) i.e. the effect of the distribution of different lattice sites on the heats of interaction with species, leads to nonlinear GB penetration plots (in Fisher's coordinates). The sign of curvature and the values of deviation from a straight concentration profile depend on the interaction ...

Grain Boundary Sliding at Serrated Grain Boundaries

Advanced Performance Materials, 1997
A constitutive model is developed for grain boundary sliding (GBS) at serrated grain boundaries. Based on a previously developed GBS model, using the dynamics of grain boundary dislocation pile-up, the present model takes the average of the sliding rate over the characteristic dimensions of grain boundary serrations.
