Title: I-V reverse bias
Post by: atk_user on March 24, 2014, 13:33

I have a question for reverse bias calculation.

When I perform the forward bias from 0 to 0.15 V, it starts from 0 V.
    biases=numpy.linspace(0,0.15,7)*Volt,

| Left electrode chemical potential  =   -3.927765 eV                          |
| Right electrode chemical potential =   -3.927765 eV                          |
| Left electrode chemical potential  =   -3.940265 eV                          |
| Right electrode chemical potential =   -3.915265 eV                          |
| Left electrode chemical potential  =   -3.952765 eV                          |
| Right electrode chemical potential =   -3.902765 eV                          |
| Left electrode chemical potential  =   -3.965265 eV                          |
| Right electrode chemical potential =   -3.890265 eV                          |
| Left electrode chemical potential  =   -3.977765 eV                          |
| Right electrode chemical potential =   -3.877765 eV                          |
| Left electrode chemical potential  =   -3.990265 eV                          |
| Right electrode chemical potential =   -3.865265 eV                          |
| Left electrode chemical potential  =   -4.002765 eV                          |
| Right electrode chemical potential =   -3.852765 eV                          |


However, when I calculate the reverse bias, it start from -0.15 V. Is that right? I think the reverse bias also start from 0 bias ....

    biases=numpy.linspace(0,-0.15,7)*Volt,

| Left electrode chemical potential  =   -3.852765 eV                          |
| Right electrode chemical potential =   -4.002765 eV                          |
| Left electrode chemical potential  =   -3.865265 eV                          |
| Right electrode chemical potential =   -3.990265 eV                          |
| Left electrode chemical potential  =   -3.877765 eV                          |
| Right electrode chemical potential =   -3.977765 eV                          |
| Left electrode chemical potential  =   -3.890265 eV                          |
| Right electrode chemical potential =   -3.965265 eV                          |
| Left electrode chemical potential  =   -3.902765 eV                          |
| Right electrode chemical potential =   -3.952765 eV                          |
| Left electrode chemical potential  =   -3.915265 eV                          |
| Right electrode chemical potential =   -3.940265 eV                          |
| Left electrode chemical potential  =   -3.927765 eV                          |
| Right electrode chemical potential =   -3.927765 eV                          |
