IV curve

[Adila]

Hi everyone,

From the attachment below, i got trend of IV curve different with others.
Is this kind of trend acceptable? or there is something wrong with method that i used?

Hi Adila. A few more details would be helpful:
- What are the details of the calculation? (python script preferred).
- What do you mean "different from others"? (what is the difference?)

[Adila]

Hi,
I attach the script that you would be helpful for you

What i meant about the IV which is different with others, is that this the first type of trend that i achieved. Therefore i am not sure whether it is acceptable or not.?

Thank you.

about charge transfer? how to calculate it?

Just looking at the plot of IV curve, an evident question why the current at 1.2 V is quite high compared with other voltage. You had better to do additional analysis for deep understanding: 1)  DOS; or 2) MPSH for the bias of 0.0 V, 1.0 V, and 1.2 V.

For the question of  charge transfer, it has been raised many times in this forum. You may search it in this forum to find related discussion, e.g,
