Title: Spin degeneracy in left/right electrode (2-probe model)
Post by: Gaurav on October 13, 2020, 15:41

Dear all,

Various approaches have been utilized to break the spin degeneracy in ZGNRs, one of them is by applying an external electric field.
I want to design a 2-probe model, where we can have half-metallic electrodes via. electric field. I have attached a sample device model for your reference. Is it the right way to design??

Thank you so much!

See the device configuration.

Your attached configuration is not the 2-probe model.
You need left/right electrode and can induce the finite electric field in the left and right electrode.
