This review for the first time systematically summarizes latest research advances of perovskite CsPbBr<sub>3</sub> crystal growth and its applications.
This review systematically summarizes the latest research advances of AlN crystals grown by PVT method and their applications.
In this paper, an ultra-high sensitivity MAPbBr 3 /NP GaN hybrid structure device was fabricated for the first time with a high current on/off ratio of about 5000 and fast response speeds 0.21/0.44 s.
Abstract The bouncing of droplets on super‐repellent surfaces normally resembles specular reflection that obeys the law reflection. Here, nonspecular droplet impingement onto solid with a dimple for energy‐efficient, omnidirectional transport is reported. With radius being comparable to droplet, all symmetries in can be broken down so endowed translational velocity finely tunable both its direction and magnitude simply by varying radii dimple, impinging position, Weber number. Tailoring...
In this study, the effect of different temperature field distributions on growth AlN crystal via spontaneous nucleation by physical vapor transport (PVT) method was investigated through simulation and experiment. The axial gradient increased from 6.71 K/cm to 10.85 K/cm, while radial 4.6 at first then decreased with rising crucible position. Combining dynamics theory, we found that main factor affecting rate crystal, driving force for expanding diameter crystal. Temperature analysis provided...
Three-dimensional numerical simulation platform for silicon carbide crystal growth furnace was established using C programing language, where a physical model of the built based on cylindrical coordinates; governing equations electromagnetic and temperature fields were discretized by finite volume method; radiation characteristics studied with help S2S (surface to surface model); least distance method proposed check faces visibility efficiently.

Monodisperse polyvinyl alcohol (PVA) microspheres have been widely used for targeted drug delivery, embolization, and templates. However, the fast facile fabrication of PVA with uniform size internal structure good sphericity remains a challenge. In this study, uniformity in size, shape, were rapidly fabricated, using single-emulsion droplet templates by an on-chip approach. First, we designed polydimethylsiloxane (PDMS) microfluidic chip integrated three functional units, generation, mixing...

In this paper, a transient numerical simulation method is used to investigate the effects of two furnace configurations on thermal field: shape melt–crystal (M/C) interface and stress in growing multicrystalline ingot. First, four different power ratios (top side power) are investigated, then three positions (i.e., vertical, angled, horizontal positions) insulation block compared with conventional setup. The ratio results show that descending ratio, M/C becomes flatter solidified ingot...
Developing high-quality monocrystalline graphene has been an area of compelling research focus in the field two-dimensional materials. Overcoming growth cessation presents a significant challenge advancing production graphene.

Comparative analysis revealed that each dynamic regulation method significantly increased size compared to samples grown under stable pressure...
Monocrystalline graphene growth has always been an intriguing research focus. Argon (Ar) is merely viewed as a carrier gas due to its inert chemical properties throughout the whole procedure by vapor deposition method.
