← ScienceWhich outcome occurs when a high-energy particle impacts a crystal lattice?
A)Knock-on displacement generates lattice defects✓
B)Auger recombination increases conductivity
C)Compton scattering shifts photon wavelength
D)Phonon bottleneck initiates thermal runaway
💡 Explanation
Knock-on displacement creates lattice defects because the particle transfers enough energy to displace atoms; therefore, increased vacancies and interstitials appear in the lattice rather than other forms of electronic interaction or thermal effects.
