Electron beam damages in zeolites: A review

2016, UltramicroscopyCitation Excerpt :Lastly, the observed behavior of the nanocubes was strongly influenced by the presence of a carbon layer, which acted to raise the dose-rate threshold substantially. This observation is not without precedent; it has been reported that carbon coatings ameliorate beam-induced damage in metals [26], organics [9,10], and oxides [3,33]. Here it is believed that the carbonaceous layer is a physical barrier that inhibits facile desorption of the oxygen atoms.
Electron-induced Ti-rich surface segregation on SrTiO<inf>3</inf> nanoparticles
2015, MicronCitation Excerpt :However, the quantification shows a substantial increase of Ti/O ratio on the islands compared to the bulk region. The results in this study are similar to previous results of high temperature treatment of SrTiO3 under reducing conditions, as well as electron-beam radiolytic damage studies of other oxides (e.g. (Ai et al., 1993; Fan and Marks, 1989; McCartney et al., 1991; Petford et al., 1986; Strane et al., 1988; Zhang and Marks, 1989)). The electron beam irradiation as well as the high vacuum almost certainly created a reducing environment on SrTiO3 nanocuboids.
Control of radiation damage in the TEM
2013, UltramicroscopyCitation Excerpt :Electron-beam damage to metal oxides may involve surface desorption induced by electronic transitions (DIET) [46,47]. Covering TiO2 with a graphitic carbon layer has been reported to slow down the formation of a highly-defective (almost amorphous) surface layer by a factor of more than 200 [48]. Reducing the incident-beam current lengthens the time needed to record an image or spectrum, increasing the likelihood of specimen, electron-beam or high-voltage drift.
