  • GaN Industry Applications

    The application areas of SiC-based and Si-based GaN are not strictly separated. In GaN-On-SiC devices, the cost of SiC substrate is relatively high, and with the growing maturity of SiC long crystal technology, the cost of the device is expected to fall further, and it is used in power devices in the field of power electronics.

  • Introducing Physical Vapor Transport (PVT) 

    SiC's own characteristics determine its single crystal growth is more difficult. Due to the absence of Si:C=1:1 liquid phase at atmospheric pressure, the more mature growth process adopted by the mainstream of the semiconductor industry can not be used to grow the more mature growth method-straight pulling method, the descending crucible method and other methods for growth. After theoretical calculations, only when the pressure is greater than 105 atm and the temperature is higher than 3200 ℃, can we get the stoichiometric ratio of Si:C = 1:1 solution. pvt method is currently one of the more mainstream methods.

  • Applications of Gallium Oxide Wafer

    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.

  • Applications of TaC Coated Graphite Components

    In the process of growing SiC and AlN single crystals by the physical vapor transport method (PVT), components such as the crucible, seed crystal holder and guide ring play a vital role. During the preparation process of SiC, the seed crystal is located in a relatively low temperature region, while the raw material is in a high temperature region exceeding 2400°C. The raw materials decompose at high temperatures to form SiXCy (including Si, SiC₂, Si₂C and other components).

  • Research Progress of TaC Coatings on Carbon-Based Material Surfaces

    Carbon-based materials such as graphite, carbon fibers, and carbon/carbon (C/C) composites are known for their high specific strength, high specific modulus, and excellent thermal properties, making them suitable for a wide range of high-temperature applications. These materials are widely utilized in aerospace, chemical engineering, and energy storage. However, their susceptibility to oxidation and corrosion in high-temperature environments, along with poor scratch resistance, restricts their further application.

  • Application of GaN

    There are many types of gallium nitride (GaN), with silicon-based GaN being the most discussed. This technology involves growing GaN materials directly on a silicon substrate.
