overcome bandgap block

[xiaolight]

in the FeCl2-MoS2-FeCl2 device, the transmission at the fermi level of both parallel and anti-parallel spin situation is pretty small due to the band gap region blocking the carrier, so how can I  solve this problem，should I add bias on the electrode or something else.

[Petr Khomyakov]

You can apply a bias voltage, or you may also add a gate electrode to apply a gate voltage, or do both at the same time.

Thank you, and if I want to add another horizontal line in the figure, like the energy at 1.1ev, can quantumwise do that?
