Simulated Operational Characteristics of a High- T{sub}c Terahertz (THz) Thermal Sensor

摘要

A solution of the time-dependent heat transfer differential equations for the two-temperature (electron and phonon) model for the sensor-lattice and the lattice-substrate interface system is used for a computational analysis of the operational characteristics, for a high-T{sub}c heterodyne thermal sensor. Responsivity and conversion gain of the sensor are analyzed in particular reference to external control parameters, e.g. the bias currents and voltages. Some operational characteristics in the form of three-dimensional graphics of the sensor are presented.
