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
Oc Their produced photons are due to injected holes having a low drift
velocity only in p-side of the junction
O d. 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.
