All‐inorganic CsPbI3 perovskite solar cells (PSCs) have been extensively studied due to their high thermal stability and unprecedented rise in power conversion efficiency (PCE). Recently, the champion PCE of CsPbI3 PSCs has reached up to 21%; however, it is still much lower than that of organic–inorganic hybrid PSCs. Interface modification to passivate surface defects and minimize charge recombination...
Recently, all‐inorganic halide perovskite (CsPbX3, (X = Cl, Br, and I)) nanocrystals (NCs) based hybrid architectures have attracted extensive attention owing to their distinct luminescence characteristics. However, due to stress and lattice mismatch, it is still a challenge to construct heterojunctions between perovskite NCs and the nanostructures with different lattice parameters and non‐cubic contour...
Microenvironment‐responsive supramolecular assemblies have attracted great interest in the biomedical field due to their potential applications in controlled drug release. In this study, oxidation‐responsive supramolecular polycationic assemblies named CPAs are prepared for nucleic acid delivery via the host–guest interaction of β‐cyclodextrin based polycations and a ferrocene‐functionalized zinc...
In article number 1903159, Qingliang Feng, Tianyou Zhai, Hua Xu, and co‐workers demonstrate the linear dichroism of trilayer 1T′ MoTe2 single crystals. The anisotropic complex refractive indices of 1T′ MoTe2 are experimentally obtained using Pinier equation analysis. This work opens up an opportunity to investigate the optical application of anisotropic semimetal 2D materials.
Semimetal 1T′ MoTe2 crystals have attracted tremendous attention owing to their anisotropic optical properties, Weyl semimetal, phase transition, and so on. However, the complex refractive indices (n‐ik) of the anisotropic semimetal 1T′ MoTe2 still are not revealed yet, which is important to applications such as polarized wide spectrum detectors, polarized surface plasmonics, and nonlinear optics...
