Pyroelectric Response of Strain Limited III-V Semiconductor
Main Article Content
Abstract
Under the anisotropy of boundary conditions, a high-gap III-V semiconductor indicates a behavior of pyroelectric crystal (in spite of it is a piezoelectric only). Partial limitation of strain in the [111]-plate of this crystal provides its substantial electric response to time-variation of temperature dT(t) or pressure dp(t). Herewith the voltage sensitivity of semi-insulating GaAlAs or GaN sensor is close to one of the PZT ceramics. However, PZT cell-transducer used as sensor device needs a hybrid integration with semiconductor amplifier. Unlike of this, if sensor device is based on the III-V crystal, transducer and amplifier are various parts of one crystal chip.
