Parameters of A Semiconductor That Resists Oxidation At High Temperatures Silicon Carbide
The semiconductor parameter of silicon carbide (SiC) at high temperatures is typically around 460°C (1958°F). However, this value can vary depending on the specific design and manufacturing process used.
One potential challenge in using SiC for optical applications such as sensors or displays is its thermal instability. SiC has a high heat capacity at very high temperatures, which means that it can quickly warm up to high temperatures even under low levels of stress. This can lead to damage to the semiconductor components if not handled properly.
Another potential issue is the need to maintain constant temperature during production. SiC requires precise control over temperature and humidity to ensure proper processing and function. Additionally, SiC materials have high melting point and will eventually begin to cool down, so it’s important to minimize this heating and cooling cycle when producing high-temperature products.
Overall, while SiC may be a suitable material for some applications, careful attention to design and manufacturing processes can help mitigate these challenges and ensure efficient use.
