    • A disclosed electrical cell enables experimental measurements of dielectric properties of an electrochromic material in the radio-frequency range of the electromagnetic spectrum. In an example embodiment, the electrical cell includes a layer of the electrochromic material under test that is sandwiched between a conducting base plane and a microstrip line. The conducting base plane and the microstrip line are electrically connected to a co-planar waveguide configured for application of superimposed DC-bias and RF-probe signals using a conventional probe station and a vector network analyzer. The S-parameters of the electrical cell measured in this manner can then be used, e.g., to obtain the complex dielectric constant of the electrochromic material under test as a function of frequency.

    • A measuring unit applies a dc voltage causing an inversion layer to be formed on an interface between a semiconductor substrate and an insulating film to the semiconductor substrate while changing a change speed of a level of the dc voltage, and measures a current flowing through the insulating film. An arithmetic unit obtains a straight line showing a relationship between the current flowing through the insulating film and the change speed of the dc voltage on the basis of a relationship between the current measured by the measuring unit and the dc voltage, and calculates a slope of the obtained straight line as surface capacitance of the insulating film. The arithmetic unit calculates permittivity of the insulating film on the basis of the calculated surface capacitance, an area of contact between a probe and the insulating film and a thickness of the insulating film.
