The research systematically integrates three core objectives: first, quantifying macroscopic device degradation—including insertion loss, modulation bandwidth, half-wave voltage, and single-event burnout susceptibility—as a function of ion species, fluence, electrical bias, and device architecture; second, characterizing the microscopic defect landscape by identifying the types, energy levels, and spatial locations (e.g., interfaces, sidewalls, bulk) of radiation-induced electrically active defects; and third, establishing a direct defect-performance correlation that maps these microscopic defects to specific macroscopic performance losses, thereby revealing the underlying physical mechanisms to enable the development of robust TFLN devices for extreme environment applications. 有意者请将个人简历及其他有助于申请的材料发送至 yue.liu@xjtlu.edu.cn。 注: 不用跟帖，直接发邮件就行，主题请注明博士申请。 |
