Is it possible that accumulation capacitance at 1MHz is higher than 10kHz on C-V curve of MIS-capacitor?

I measured C-V by changing the frequency from 10kHz to 1MHz. Typically, jigger frequencies have lower capacitance compared to 10kHz at the accumulation regime of Al/HfO2/p-Si MIS-diode. In this...
