Defects widely exist in real crystals, and they play an important role in the properties of solids. Point defects are atomic defects whose effects are limited only to their immediate surroundings [8]. Examples are ionic vacancies in the regular crystal lattice, or interstitial atoms or ions. Ion...

Perovskite Quantum Dots and Their Application in Light‐Emitting Diodes Perovskite quantum dots (PQDs) attract significant interest in recent years because of their unique optical properties, such as tunable wavelength, narrow ... Wang, Hung-Chia,Z Bao,Tsai, Hsin-Yu,... - 《Small》 被引量: ...
Whether hydrated from vapor or immersed in liquid water, aligned multibilayers of dimyristoylphosphatidylcholine adsorbed to a single mica "substrate" are shown by neutron diffraction to hydrate in all mesophases (e.g., L β′ , P β′ , and Lα) to the same extent as their liposomal count...
Calcite (Calcium Carbonate, CaCO3) is a very common mineral that comes in a wide variety of forms, shapes and colors. Thetrigonalcrystals range from translucent to transparent. Transparent calcite exhibits a double refraction effect (when you look through the crystal, singel items are doubled)....
One possible solution against the accumulation of petrochemical plastics in natural environments is to develop biodegradable plastic substitutes using natural components. However, discovering all-natural alternatives that meet specific properties, such a
To meet this requirement in the experiment, we split a single laser beam into three and pump three SPDC sources in parallel. Photon pairs are thus generated in separate nonlinear crystals. However, as the pump beams are generated by the same laser, correlations may still be present. In ...
These studies were undertaken for understanding the role of the A cation in their band structure and band gap energy characteristics. The calculations were initiated by finding the optimum lattice constants and the lowest total energy of these APbBr3 crystals. Ultrasoft pseudopotentials with GGA-PBE ...
Surface organic ligands are critical in determining the formation and properties of atomically precise metal nanoclusters. In contrast to the conventionally used thiolate, phosphine and alkynyl ligands, the amine ligand dipyridylamine is applied here as
approximation ofA1andA2are shown in separate curves labeled with “No pol.A1” and “No pol.A2”, respectively. The space between the simulation data points is linearly interpolated.cSame as (b) but the cosine similarity between the all-optical transforms and their ground truth shown in (a)...
