Which outcome results when rapid cooling stresses a gallium arsenide crystal?

💡 Explanation

An increased point defect concentration results because rapid cooling introduces non-equilibrium vacancies via **thermal shock**, therefore vacancies form along grain boundaries rather than maintaining crystalline order; enhanced electron mobility and reduced scattering are possible rather than alternatives.
