电弧等离子体沉积系统

电弧等离子体沉积系统-APD

APD设备特点

◆  系统可以通过调节放电电容选择纳米颗粒沉积直径在1.5nm到6nm范围内。

◆  只要靶材是导电材料，系统就可以将其等离子体化。（电阻率小于0.01ohm·cm）。

◆  改变系统的气氛氛围，可以制备氧化物或氮化物。石墨在氢气中放电能产生超纳米微晶钻石。

◆  用该系统制备的活性催化剂效果优于湿法制备。

◆  Model APD-P支持将纳米颗粒做成粉末。Model APD-S适合在2英寸基片上制备均匀薄膜。

APD技术原理

1、在触发电极上加载高电压后，电容中的电荷充到阴极（靶材）上；
2、真空中的阳极和阴极（靶材）间，电子形成了蠕缓放电，并产生放电回路，靶材被加热并形成等离子体；

3、通过磁场控制等离子体照射到基底上，形成薄膜或纳米颗粒。

材料适用性：

APD适用于元素周期表中大部分高导电性金属，合金以及半导体。所用原料为直径10mmX17mm长圆柱体或管状体，且电阻率小于0.01 ohm.cm。下面的元素周期表显示了可制备的材料，绿色代表完全适用，黄色代表在一定条件下适用。
