- If the maximum atom or ion energies in a collision cascade are higher than the threshold displacement energy of the material ( tens of defects.
- Most of the displaced atoms resulting from electron irradiation and some other types of irradiation are PKAs, since these are usually below the threshold displacement energy and do not have sufficient energy to displace more atoms.
- They can also be used to estimate the damage produced in materials, by using the assumption that any recoil which receives an energy higher than the threshold displacement energy of the material will produce a stable defect.
- The result of a radiation damage event is, if the energy given to a lattice atom is above the threshold displacement energy, the creation of a collection of point defects ( vacancies and interstitials ) and clusters of these defects in the crystal lattice.
- In linear cascades the set of recoils produced in the sample can be described as a sequence of recoil generations depending on how many collision steps have passed since the original collision : primary knock-on atoms ( PKA ), secondary knock-on atoms ( SKA ), tertiary knock-on atoms ( TKA ), etc . Since it is extremely unlikely that all energy would be transferred to a knock-on atom, each generation of recoil atoms has on average less energy than the previous, and eventually the knock-on atom energies go below the threshold displacement energy for damage production, at which point no more damage can be produced.
- It's difficult to see threshold displacement energy in a sentence. 用threshold displacement energy造句挺難的
