In the field of single crystal growth, the temperature distribution within the crystal growth furnace plays a critical role. This temperature distribution, commonly referred to as the thermal field, is a vital factor that influences the quality and characteristics of the crystal being grown. The thermal field can be categorized into two types: static and dynamic.

The four main molding methods for graphite molding are: extrusion molding, molding, vibratory molding and isostatic molding. Most of the common carbon/graphite materials on the market are molded by hot extrusion and molding (cold or hot), and isostatic molding is a method with leading molding performance. Vibration molding is generally used to manufacture medium and coarse structural graphite, particle size between 0.5-2mm particle size, generally dominated by di-roasted graphitized products, density between 1.55-1.75kg/m³, coarser particles, rougher surface, can not be used for precision machining. It is mainly used in chemical industry and metal smelting.

Gallium oxide (Ga2O3) has emerged as a promising material for various applications, particularly in power devices and radio frequency (RF) devices. In this article, we explore the key opportunities and target markets for gallium oxide in these domains.

Homoepitaxy and heteroepitaxy play pivotal roles in material science. Homoepitaxy involves the growth of a crystalline layer on a substrate of the same material, ensuring minimal defects due to perfect lattice matching. In contrast, heteroepitaxy grows a crystalline layer on a different material substrate, which can lead to challenges like lattice mismatch. These processes are crucial in advancing semiconductor devices and thin films. For instance, heteroepitaxy significantly impacts microelectronics and quantum optics, contributing to innovations like Light Emitting Diodes.

In the process of silicon wafer manufacturing, after the crystal rod is cut into silicon wafers, it will need to be polished and cleaned to obtain a single crystal silicon wafer like a mirror.

The third generation of semiconductor materials AlN belongs to the direct bandgap semiconductor, its bandwidth of 6.2 eV, with high thermal conductivity, resistivity, breakdown field strength, as well as excellent chemical and thermal stability, is not only an important blue light, ultraviolet materials, or electronic devices and integrated circuits, important packaging, dielectric isolation and insulation materials, especially for high-temperature high-power devices. In addition, AlN and GaN have a good thermal match and chemical compatibility, AlN used as GaN epitaxial substrate, can significantly reduce the defect density in GaN devices, improve device performance.
