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NO_(2)传感器提供一种简单的增强方法。A strategy for the sensing properties enhancement ofα-6T-based sensor was proposed in this paper.Through hydrothermal method and organic thermal evaporation,α-6T/zinc oxide(ZnO)layered composite sensors with differentα-6T thicknesses were prepared.Compared withα-6T sensor,the optimized composite sensor obtained a higher response(2.14 times of pristineα-6T),faster response(18.81%of pristineα-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 forα-6T-based NO_(2) sensor.
