In semiconductor manufacturing, PN junction is formed by introducing dopants to activate neighboring electron and hole conductance. To avoid structural distortion and failure, it generally requires the foreign dopants localize in the designated micro-areas. This, however, is challenging due to an inevita...
In thermodynamic equilibrium the Fermi level is horizontal throughout the crystal, thereby forcing both conduction and valence bands to bend, creating the pn -junction (see Figure 2b). Electrons from the p -type region will thereby "roll down" the hill and holes from the n -type region will...
(bottom panelin Fig.2d). On the other hand, the built-in field increases by applying a positive gate bias with the Fermi level in the N-MoS2moving towards the conduction band. This facilitates a more efficient charge separation across the PN junction (top panelin Fig.2e) as well as the...
