← ScienceWhich mechanism inhibits thermal runaway during gallium arsenide solidification?
A)Latent heat of fusion release✓
B)Increased convection heat transfer
C)Reduced interface surface roughness
D)Solidification-induced impurity segregation
💡 Explanation
Thermal runaway is slowed by the isothermal phase change at the melting point because solidification liberates the latent heat of fusion, thereby absorbing energy rather than further raising temperature. Increased convection would assist a runaway; therefore, it's not correct.
