查询词典 bombardment

The native oxides on CdSe surface could be reduced to elemental Selenium by a HF etching process. Bombardment using 100eV Ar〓 ions with a dosage of about 1×10〓 ions/cm〓 could remove all the elemental Selenium, which results in a normal stoichiometrical surface CdSe.

实验观测到HF刻蚀可以将CdSe半导体表面的Se氧化物还原为元素Se.100eV的Ar〓离子轰击可以除去HF刻蚀后在表面还原生成的元素Se，从而清洁样品表面，保证了表面CdSe的化学计量比。
