摘要

采用夹心金属二morphite(As/sub 4/S/sub 3/)金属结构作为检测丙胺(P/sub r/NH/sub 2/)蒸气的传感器。从二晶膜的形貌出发，研究了气致电流-电压特性的气致位移以及气致电流的瞬态特性。丙胺蒸气导致电流增大，即具有掺杂效应。灵敏度与外加电压和气体浓度有关。在影响空间电荷限制电流(SCLC)的电极注入载流子的气控俘获主题中讨论了结果。

A new propylamine sensor using artificial dimorphite

The sandwich metal-dimorphite(As/sub 4/S/sub 3/)-metal structure is used as a sensor for detection of propylamine (P/sub r/NH/sub 2/) vapor. The gas induced shifts of the current-voltage characteristics as well as transient characteristics of gas-induced current are studied with respect of morphology of dimorphite films. Propylamine vapor lead to increasing of current i.e. has a doping effect. Sensitivity dependence on applied voltage and on gas concentration is found. Results are discussed in themes of gas controlled trapping of carriers injected from electrodes which influence the space charge limited current (SCLC).
