Silicon Carbide (SiC) is a key material due to its superior properties for space applications. Our material growth process involves:
We use the CSS method to grow SiC layers with precise control over thickness and doping levels. This ensures that our power converters have the ideal electrical properties for efficient energy conversion.
Our process includes both n-type and p-type doping to achieve optimal performance. We focus on minimizing defects and enhancing the carrier mobility, which is essential for high-efficiency power conversion.
We utilize different SiC polytypes, such as 3C, 4H, and 6H, depending on the specific requirements of the laser power transmission system, ensuring that each application is matched with the ideal material characteristics.
Once the SiC material is grown, it moves into the device fabrication phase. This involves transforming the raw material into a functioning power conversion device that can be integrated into our laser transmission system:
We develop both vertical (vLPC) and horizontal (hLPC) laser power converters to suit different application needs. Vertical structures allow for reduced resistance and higher efficiency, while horizontal structures are ideal for certain compact configurations.
Precision techniques such as deep trenching are used to minimize losses, while metallization ensures low-resistance contacts, critical for efficient power extraction.
Initial prototypes are developed to validate the material properties and overall design. The fabrication process is iteratively refined based on testing feedback to achieve the highest performance.
Fabricating devices for space requires attention to durability and resilience under extreme conditions:
The fabricated devices are designed to withstand high levels of radiation, which is essential for long-term stability in orbit or deep space missions.
Our devices are built to operate at high temperatures without degradation, ensuring consistent performance even in the harsh conditions of space.
The Material Growth and Device Fabrication phase bridges the gap between theoretical design and practical implementation. By ensuring that our SiC materials are of the highest quality and that our devices are precisely fabricated, we lay a solid foundation for successful integration into the RePowerSiC laser power transmission system.
This phase is vital to transforming the innovations envisioned in our models into tangible, high-performance systems ready for deployment in space exploration missions. Through rigorous growth processes and careful fabrication, RePowerSiC is making the vision of efficient, sustainable space power transmission a reality.
