【摘要】 提出了一种基于结构优化特性优化的α-6T的传感器敏感特性增强方法。通过水热法和有机热蒸发，制备了不同α-6T厚度的α-6T/氧化锌（ZnO）层状复合气体传感器。与单一α-6T传感器相比，优化后的复合传感器具有更高的响应（是单一α-6T的2.14倍）、更快的响应（是单一α-6T传感器的18.81%）。此外，基于形态学特性和异质结理论分析建立了α-6T/ZnO复合薄膜的敏感特性增强机制。研究为基于α-6T的NO₂传感器提供一种简单的增强方法。更多还原

【Abstract】 A strategy for the sensing properties enhancement of α-6T-based sensor was proposed in this paper.Through hydrothermal method and organic thermal evaporation,α-6T/zinc oxide （ZnO） layered composite sensors with different α-6T thicknesses were prepared.Compared with α-6T sensor,the optimized composite sensor obtained a higher response （2.14 times of pristine α-6T）,faster response （18.81%of pristine α-6T sensor）.Moreover,the sensing enhancement mechanism was analyzed based on both morphology properties and heterojunction theory.This work could provide a facile enhancement strategy for α-6T-based NO₂ sensor.更多还原
