What are the responsibilities and job description for the Sensors and microelectromechanical systems for missions to hot planets position at National Aeronautics and Space Administration (NASA)?
In the last few years we have seen rapid growth of III-V semiconductors geared towards a variety of applications where silicon performance falls short. Gallium nitride (GaN), a III-V semiconductor, is proven to be the material of choice for high- frequency, high-power, and high-temperature applications. GaN also offers a number of excellent mechanical properties, making it a suitable material for MEMS. Particularly, GaN and its related material family are very interesting for harsh environment applications. Beyond earth, GaN based microsystems can enable low-cost and long-lasting planetary exploration missions to hot planets. Our research objective is to develop a sensor technology platform that is temperature and radiation tolerant using gallium nitride MEMS technology. In this specific project the postdoc will help with developing temperature stable sensors and micro-instruments working at 500C using GaN based acoustic and micromechanical components.
