充氮

Evacuate the equipment and break vacuum with an inert gas, such as nitrogen.

对设备抽真空，然后充入不活泼气体，如氮。

H-BN thin films were prepared on the (100)-oriented surface of n-Si by r.f. sputtering physical vapor deposition.

利用射频磁控溅射方法，真空室中充入高纯N2(99.99%)和高纯Ar(99.99%)的混合气体，在n型(100)Si基底上沉积了六角氮化硼薄膜。

H-BN thin films were prepared on the (100)-oriented surface of n-Si by r. f. sputtering physical vapor deposition. The field emission characteristics of the BN films were measured in a ultra high vacuum system. It has been found that the field emission characteristics of BN films is affected evidently by substrates temperature.

利用射频磁控溅射方法，真空室中充入高纯N2(99.99%)和高纯Ar(99.99%)的混合气体，在n型(100)Si基底上沈积了六角氮化硼薄膜，在超高真空0^(-7Pa系统中测量了BN薄膜的场发射特性，发现沈积时基底温度对BN薄膜的场发射特性有很大影响。
