Which outcome occurs when a high-intensity laser ablates a crystalline silicon wafer?

💡 Explanation

When a high-intensity laser ablates the silicon, rapid heating and cooling cause a breakdown in the crystal structure through the mechanism of rapid solidification. This results in amorphous regions near the ablation site because the atoms lack sufficient time to arrange into a crystalline lattice; therefore structural defects form rather than increased order.
