Question

write a short note on why do we use semiconductor for making optoelectronic devices

​

Answer 1

Answer:

I no tell your answer answer is long and difficult

Answer 2

Answer:

optoelectronic devices such as electric fields in the form of applied voltages or band-bending due to doping are usually utilized to separate the charge carriers. In the exciton picture, these electric fields oppose the Coulomb attractive interaction between the electrons and the holes, and may cause dissociation of the exciton. Thus, understanding the impact of electric fields on excitons is important for device design, and to evaluate when the single particle, band-to-band picture might be appropriate.
