Thermal engineering in semiconductor heterojunction for space transducers

微机电系统（MEMS）换能器，包括传感器和致动器，是必不可少的空间应用。然而，MEMS换能器尚未为航天工业提供令人信服的性能，因为它们在经受高温和辐射时通常会经历性能退化。该研究旨在开发一种创新的传感器技术，该技术使用温度梯度来提高性能，并使用抗辐射材料来确保可靠性和寿命。预期成果包括更好地了解温度梯度下的传感器性能，适当的材料选择，以及空间和国防应用高性能传感器的设计建议。

Microelectromechanical system (MEMS) transducers, including sensors and actuators, are essential for space applications. However, MEMS transducers have not yet provided compelling performance for the space industry as they typically experience degradation of performance when subjected to elevated temperature and radiation. This research aims to develop an innovative transducer technology that uses a temperature gradient to enhance performance and a radiation-hard material to ensure reliability and longevity. Expected outcomes include improved understanding of transducer performance under temperature gradient, appropriate material selection, and design recommendations for high-performance transducers with applications in space and defence.
