b) A Si p'n abrupt junction with No=10¹7 cm³ (i) Derive the approximate expression of the maximum electric field E. in the depletion region. (ii) Calculate the breakdown voltage VR when E= Ecrit = 7x105 V/cm. Parameters of Si at T-300K: Eg=1.12eV, ni = 1.5x100 cm³, &=11.9, KT = 0.0259 eV. b) A Si p'n abrupt junction with No=10¹7 cm³ (i) Derive the approximate expression of the maximum electric field E. in the depletion region.
