Which outcome occurs when a pulsed laser anneals polysilicon?

💡 Explanation

During laser annealing, larger grains grow by the mechanism of Ostwald ripening because smaller, high-energy grains dissolve, therefore the average grain size increases, rather than reducing the overall crystallinity or reversing vacancy gradients.
