Abstract

An infrared detector using a photoeffect in mercury selenide is described which responds from the visible to 15 μ. Although the detector construction and sample geometry are similar to that employed in the photoelectromagnetic (PEM) effect, performance differs from that expected of the PEM effect. The spectral response for constant power input per unit wavelength interval peaks in the visible and is wavelength independent in the interval from 3 to 15 μ. The frequency response indicates a detector response time of 150 μsec. A thermal response mechanism is proposed.
