Which outcome occurs when a silicon ingot cools unevenly during semiconductor crystallization?

💡 Explanation

When unequal stresses occur during cooling, thermoelastic stress generates dislocations because regions of the silicon crystal deform under differential heating causing lattice imperfections to propagate. Therefore, increasing dislocation density results, rather than formation of polycrystals, impurity segregation, or dopant changes, which arise from other mechanisms and conditions.
