It should be possible to correlate the hysteresis loops and the corresponding C-V characteristics quantitatively and qualitatively.

Shifts along the voltage axis can be related to built in fields due to defects.

There are just too many paper dealing with such analysis. Of course you may to go back in the literature (1985 to 1990) where such effects have been analysed in great detail.
