Which outcome occurs when a pulsed laser etches silicon?

💡 Explanation

Material removal occurs because the pulsed laser focused onto silicon causes rapid heating and instantaneous vaporization, known as material ablation. Therefore, a precise amount of material is removed, rather than uncontrolled melting; direct electron excitation alone isn't sufficient.

• Which outcome occurs when reactants pass through zeolites?
• Which consequence accelerates corrosion when dissimilar metals join via seawater electrolyte containing sodium chloride?
• Which outcome occurs when pressure exceeding silicon's yield strength?
• Which outcome occurs when unpolarized light encounters dichroic filter material?
