← ScienceWhich voltage is generated when doping alteration ends abruptly?
A)Dember voltage carrier separation✓
B)Peltier voltage thermal gradient
C)Seebeck voltage material interface
D)Hall voltage magnetic deflection
💡 Explanation
Dember voltage arises because differences in electron and hole mobility yields nonuniform carrier separation following photoexcitation; therefore, a voltage develops rather than immediate recombination because faster carriers diffuse further into regions.
