(Answered) State which of these two mechanisms, diffusion or drift, is dominant in forward bias and which one…

➤ Why does diffusion dominate under forward bias?
Because forward bias reduces the barrier, carrier concentration gradients become the driving force. Electrons and holes are injected into opposite regions, creating strong concentration gradients that cause diffusion. This diffusion of minority carriers controls current and recombination in quasi-neutral regions, producing the exponential I–V relation typical of diodes under forward bias.
