Thermal engineering in semiconductor heterojunction for space transducers

微机电系统（MEMS）换能器，包括传感器和执行器，在空间应用中是必不可少的。然而，MEMS换能器尚未为航天工业提供令人信服的性能，因为它们在受到高温和辐射时通常会出现性能下降。这项研究旨在开发一种创新的换能器技术，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使用寿命。预期结果包括提高对温度梯度下换能器性能的理解，适当的材料选择，以及在空间和国防领域应用高性能换能器的设计建议。

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.
