摘要: 通过化学气相沉积法(CVD)制备了三氧化二铁(αFe2O)六角晶体,后对制得的αFe2O3进行了系列表征,对反应机理进行了分析。同时构建了场效应晶体管(FET)考察了材料电学性能,并测试了器件对一氧化碳(CO)的气敏性能。实验表明:以三氯化铁(FeCl3)和水蒸汽(H2O)为原料通过CVD方法能够在相对温和的条件下制备准二维αFe2O3六角晶体;用制得的材料构建场效应晶体管具有良好的电学性能,并对CO气体具有很好的响应。

Abstract: Hexagonal crystalline of ferric oxide are prepared by chemical vapor deposition.Then we conducted a series of characterization of αFe2O3 crystal, and briefly discussed the reaction mechanism. The field effect transistor was constructed to investigate the electrical properties of the materials and the gas sensing of carbon monoxide were tested. The experimental results show that ferric oxide can be prepared under relatively mild conditions with ferric chloride and water vapor as raw materials. The field effect transistor constructed with the prepared materials have a good response to carbon monoxide.

 

Key words: chemical vapor deposition; αFe2O3; field effect transistor; carbon monoxide
