Vedclass · Answer

(A) In a semiconductor,the mobility of charge carriers is defined as the drift velocity per unit electric field. Electrons are lighter and move through the conduction band,whereas holes are essentially vacancies in the valence band that move through a process of successive electron jumps. Due to their lower effective mass and the nature of their movement in the conduction band,electrons encounter less scattering and have a higher mobility compared to holes. Therefore,the mobility of electrons is always greater than the mobility of holes,i.e.,$\mu_e > \mu_h$.

In a semiconducting material,the mobilities of electrons and holes are $\mu_e$ and $\mu_h$ respectively. Which of the following is true?
