Summary: In this study, 4H-SiC Schottky diodes with a sensitive area of 7 x 7 mm2 were fabricated and their temperature-dependent performances were analyzed. The results showed positive correlations between temperature and ideality factor, barrier height, and leakage current, while negative correlations were observed between temperature and on-resistance, series resistance, and built-in potential voltage. The diodes exhibited low leakage current and large rectification ratio, indicating their high quality. Additionally, the response characteristics of a Ni/4H-SiC detector were investigated under alpha source irradiation, providing insights for radiation detection applications at high temperature.

Summary: Transition-metal dichalcogenides (TMDs) in flexible technology provide scalability, integration, and low power consumption. However, the high process temperature of TMDs hinders their incorporation in large-area flexible platforms for data storage. Low-temperature growth of TMDs bridges this gap and simplifies the transferring process.
