How can I determine interface state density distribution of a Schottky barrier diode from a C-V characteristics?

You can perform the C-V measurements at two different frequencies (one about 10 kHz and another about 1 MHz) and then by the simple calculations (see attached reference) you can estimate the interface state density:
