← ScienceWhich outcome occurs when a rapidly pulsed laser induces localized heating within a crystalline semiconductor lattice?
A)Ablation above the material's melting point✓
B)Increased thermoelectric Seebeck coefficient magnitude
C)Enhanced grain growth within the matrix
D)Increased equilibrium carrier recombination lifetime
💡 Explanation
Laser-induced heating causes ablation because rapid energy deposition leads to exceeding the melting point and subsequent material removal in the process of thermal ablation. Other options entail slower, equilibrium processes; therefore ablation occurs from localized, rapid heating rather than grain growth that requires more time.
