The charge related to esd can be compensated by oxygen environment , oxygen environment works mainly through making up oxygen vacancy and repairing energy band distortion in time . heating the sample and reducing defect concentration can reduce the charge related to inner defects 對(duì)于樣品表面電子受激解吸造成的充電可通過(guò)氧環(huán)境提供補(bǔ)償,氧環(huán)境主要是通過(guò)及時(shí)補(bǔ)充氧空位、修復(fù)能帶扭曲起作用的;對(duì)于電子束調(diào)制內(nèi)部缺陷造成的充電可通過(guò)加熱試樣減輕缺陷濃度來(lái)補(bǔ)償。
