Bulk crystal of tetragonal CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub>with dimensions centimeters grown by a temperature-lowering method in HI solution is reported for the first time.
Ternary metal halides with large exciton binding energy have recently gained considerable attention in the optoelectronic field due to their high photoluminescence quantum yield and Stokes shift. Here, efficient scintillators are designed based on these advantageous properties. For first time, bulk Cs3Cu2I5 is grown using a melt method other than intensively reported solution growth, behaved as an intrinsic scintillator, emitting bright blue (∼450 nm) light under X-ray γ-ray irradiation....
Abstract Magnetic refrigeration around the liquid-helium temperature plays a critical role in many technological sectors. Even if gallium gadolinium garnet (GGG) has been regarded as benchmark, its application is highly limited by small magnetic entropy changes, requirement of superconducting magnets, and large device sizes. Here, we report that LiREF 4 (RE = rare earth) single crystals exhibit significantly superior magnetocaloric performance levels to commercial GGG. Under field 5 kOe,...
Designing an effective carrier‐transport layer is crucial for achieving highly crystalline silicon (c‐Si) solar cells. MoO X , with its high work function and wide bandgap, the preferred choice hole‐transport‐layer (HTL) materials in c‐Si However, limited reflection ability conductivity of rear contact lead to a decrease short‐circuit current In this study, ultrathin Au interlayer inserted between two layers construct /Au/MoO (MAM) composite HTL. First, HTL (Au) contributes upward band...

Abstract Optical isolators (OIs) are needed to protect laser sources from back‐reflections. Driven by the fast‐growing market of marking and machinery, increasing cost rare‐earth‐based permanent magnets, single‐crystalline Faraday rotators (FRs) with a large Verdet constant V highly desired reduce size OIs. Furthermore, need for finer procedures (marking, cutting, welding) is shifting used emissions toward shorter wavelengths: into visible (VIS), where standard Tb 3 Ga 5 O 12 (TGG) has poor...
