Intrinsic doping
WebSep 7, 2024 · Considering the influence of the intrinsic dipole moment on the doping level, we then try to modulate the doping level by varying the stacked Janus MXY thickness. Double-layer Janus MXY is sandwiched in between graphene layers. The band structures of the four heterostructures are revealed in figure S6 (in the supplementary material). WebAt room temperature, the Fermi energy level for a doped semiconductor is shown below. The doping concentration is 1 0 14 atoms / cm 3. The mobility of the electrons are two times larger than the mobility of the holes (μ n = 2 μ p ) and σ 0 is the conductivity of this material. The intrinsic carrier concentration is 1 0 12 cm − 3 at
