Semiconductor LED's have a slow response time and hence a low frequency operation and low band width because: O a. their produced photons are mainly due to the diffusion process of the injected carriers O b. Their produced photons are due to injected electrons having a low drift velocity only in n-side of the junction O C. Their produced photons are due to injected holes having a low drift velocity only in p-side of the junction Their produced photons are due to injected electrons and holes having a low drift velocity due to low biasing voltage. O e. Non of the given choices is correct.
