【摘要】 以ＣｄＯ、ＳｎＯ＿２粉料作为靶，采用直流溅射方法制得ＣｄＯ、ＳｎＯ＿２双层薄膜元件，比较了ＣｄＯ／ＳｎＯ＿２与ＳｎＯ＿２／ＣｄＯ在性能方面的差异。认为ＣｄＯ／ＳｎＯ＿２的气敏性能较好，并初步探讨了工作温度和膜厚等因素对ＣｄＯ／ＳｎＯ＿２元件的电学性质及气敏特性的影响。更多还原

【Abstract】 CdO/SnO₂ and SnO₂/CdO bilayerthin films were prepared by d.c.sputtering usingCdO and SnO₂ as targets.Conductance and gas-sensing properties of these bilayer films were measured,and it was found that CdO/SnO₂ bilayerfilms had a better sensitivity to reducing gases compared with that of SnO₂/CdO bilayer films. Effectsof operation temperatures and filrn thickness onconductance and gas-sensing properties of CdO/SnO₂ bilayer films were investigated.更多还原
