← ScienceWhich outcome occurs when a high-energy photon strikes an undoped silicon crystal?
A)Electron-hole pairs abruptly form✓
B)Increased crystal lattice stabilization
C)Spontaneous crystal phase transition
D)Overall reduced crystal temperature
💡 Explanation
Electron-hole pair formation occurs because the incident photon's energy exceeds silicon's band gap, therefore initiating intrinsic photoeffects rather than affecting the lattice parameters. Energy initiates Band-to-Band excitation, rather than a temperature drop occurring, as the crystal absorbs energy.
