An n-channel MOSFET on a p-type silicon wafer (see figure) has an oxide layer with a d = 12nm thickness. The doping of the p-type silicon is homogeneous and has the value 2 × 106cm³. The band gap is Eg = 1.15 eV, the dielectric constant of Si and SiO2 are € = 11.9 and 4, the longitudinal and transverse effective masses of the electron states in the conduction band are me.10.19m, and met = 0.98m, respectively, and those of the heavy and light holes in the valence band are mhh = 0.54 m and mih = 0.15m (m is the mass of an electron). E M U. >O SIO₂ 0 (²) p-Si E E₁ Questions: 1. discuss what longitudinal and transversal electron masses are and why they appear 2. Calculate the gate voltage Ug, which is necessary to bring the conduction band edge at the Si/SiO2 interface to the level of the Fermi potential µ. 3. Calculate the electric field strength at the Si/SiO2 interface and the width dp of the space charge region in the p-silicon?
