Abstract
The strip inverse-configuration photopyroelectric technique to measure the thermal conductivity of bulk samples of metals, semiconductors, and insulators is presented. It utilizes a narrow (500 \mu m wide) strip of a 9 \mu m thick pyroelectric sensor in an inverse configuration. A mathematical model is outlined that yields an expression for the output voltage of the pyroelectric sensor following heat dissipation into the sample, in a frequency range where the proposed measurement is possible. Experimentally, the sensor was operated in an "isothermal-voltage" mode to identify the frequency regime within which the measurement of the thermal conductivity of representative samples was possible after suitable calibration of the system.
