Preparation of Small Disk-shaped Samples for Capacitance and Pyroelectric Current Measurements
where C is the sample capacitance to be measured, ε0 is the vacuum dielectric permittivity, α is the cooling rate in the pyroelectric current measurement and Ip(T) is the pyroelectric current measured at a given temperature, T. Precise measurements require well-defined shapes and a high degree of parallelism of layer-shaped samples. This is difficult to …
