The conductivity for n-side is 1500 s/m and for p-side is 400 s/m in pn junction, while the conductivity of the pure silicon is 4 × 10-4 s/m. Find the barrier potential at 300°K, if the µn = 2.4µp?
Can I compare the Hall coefficient of a semiconductor I am using to another sample of the same element and type (p-type)? I have read that the Hall coefficient is dependent on the dimensions of the sample so in this case, it wouldn't be comparable. I would appreciate any guidance as i am still unsure.

Which of the following option is FALSE for n-type semiconductor materials? Lütfen birini seçin: O A. None O B. The band gap between the conduction band and the valance band is comparatively less than that of undoped semicondctor materials. O C. The number of carrier electrons is slighlty less than that of intrinsic semiconductor materials. O D. The number of conduction band electrons increases. O E. All O F. Since the number of mobile electrons get larger during the doping process, the electrons become the majority carriers.
