NASA Glenn technician Ariana Miller loads a silicon carbide wafer into an ultrahigh vacuum chamber to prepare for the deposition of a high-purity electrically conductive layer.
NASA Glenn technician Ariana Miller loads a silicon carbide wafer into an ultrahigh vacuum chamber to prepare for the deposition of a high-purity electrically conductive layer. This is a critical step in the process of fabricating silicon carbide based sensors and electronics that can operate at extremely high temperatures (500 degrees Celsius and higher) for applications such as sensor systems for aircraft engines and Venus exploration.
