Damage depth

Another basic approach of CL analysis methods is that of the CL spectroscopy system (having no electron-beam scanning capability), which essentially consists of a high-vacuum chamber with optical ports and a port for an electron gun. Such a system is a relatively simple but powerful tool for the analysis of ion implantation-induced damage, depth distribution of defects, and interfaces in semiconductors. ... 

GOI, but it can be removed by 3 times SCI cleaning, and the damage depth was about 21nm.

The first example of the application of atomistic simulation to a materi-als-related area is probably the work of Vineyard and co-workers. They used classical trajectories to model damage induced in a solid by bombardment with ions having hyperthermal kinetic energies. These calculations, which were done at about the same time as Rahman s initial studies on liquids, provided important data related to damage depth as well as new insights into many-body collisions in solids. The potentials used were continuous pair-additive interactions similar to those employed in Rahman s simulations.

The borehole inspection survey was conducted for capturing the damaged roek strata due to repeated blasting at Crown of tuimel. The images of borehole sections which contain the interface of intact and disturbed rock mass are shown in Figure 19. The maximum damage depth measured by the borehole camera survey with joint angle parallel to the tunnel profile was 3.21 m, but... 

It was proved that a grinding wheel with a larger grit size presents a larger damage depth to the grounded piece (Zhang et al., 2000). As the...

DAP in Fe-(0.1-0.3) Cu alloys after heavy ion irradiation (Pareige et al., 2001,2005). In these studies, needle-like tips with lOOnm in thickness were irradiated with 150, 180 or 300 keV Fe + ions at 573 K so that the peak damage depth, 50 nm, corresponds to the centre of the tip. The early stage of Cu-rich cluster formation was identihed. 

Very limited damage depth <1 am for MeV ions (>10pm for GeV ions)... 

In proton irradiation with MeV order energies, the major advantage is that it provides modest dose rate and damage depth, which allows hardness measurements at modest doses (0.1-10 dpa) within a reasonable irradiation period (a day or a week). Implanted H atoms are believed to have neghgible influence on material properties in Fe-based alloys at temperatures higher than room temperature. A minor limitation is radioactivation of irradiated specimens.
