When I measure C-V (frequency 1MHz) , at higher temperature, the curve drops and becomes in negative , what are the possible explanation to that ?

I have 3 thin film samples of Barium Titanate MFM structure each having different top electrode of Platinum, Palladium and Titanium , while sharing similar bottom electrode ITO . I study the electrical Charactersitics with varying two factors , Top electrode and temperature.

As your samples' resistance (e.g. the ZrealPart) is reducing (semi-conducting character) at high(er) temperature T region, then it can be comparable (or even lower) than the ZimagPart. This condition arouse towards inadequately small values of your samples' resistance[1] regime (e.g. ZrealPart[1]
