Hey All happy holidays,
Some time back I took electrical measurements on a ferroelectric capacitors in which I would apply sin or triangle waves for a certain amplitude (typically 4-5volts) and I collected/mointered/measured the current. I then was hoping to take that current and calculate the polarization of the ferroelectric capacitors and create a hysteresis but my loops were coming out garabage.
At any rate I know was looking at someone elses data collected in the same manner, but their device was able to caculate polarization on the spot. They obtained hystersis loops. Looking at their raw current data and voltage data the trends are exactly the same as mine! Which has given me hope that my data is good and i was just calculating polarization wrong.
To caculate polarization I was using taking the current and multplying it by the difference in time between each step.
Does anyone know the correct way to take current with respect to voltage and calculate polarization electrical hystersis loops?
Thanks
Nick
