simulating the hysteresis I-V curve

Asked by He Wang

Dear developers,

I'm trying to simulate a graphene-based memristor.
When I increase or decrease applied voltage to one value, the deserved current values should be different.
Is it possible to simulate the hysteresis I-V curve with transiesta ?
If it is possible, how to do the simulation?

Thanks in advance.

I am a bit reluctant to say yes, but also to say no.

In principle IFF you proceed as the hysterises curve *should* behave and the energy minimum landscape has so deep a valley to keep the SCF convergence away from the other two basins then yes, it could be possible.

However, I am very doubtful this would actually work...

Please enlighten us if you find that you *can* reproduce a hysteresis curve!

I will.
Thanks for your answer.
