Detection at 100–300 μm with Hg1-xCdxTe in a magnetic field

Abstract

At the 7th International Conference on Infrared and Millimeter Waves, Weber and Kulpa (in a distributed paper) reported enhanced response of a HgCdTe detector when operated in magnetic fields up to 30 kilogauss. However, unlike in n-InSb [1] hot electron bolometers there was no marked increase in responsivity at shorter far infrared wavelengths (compared with longer wave inhancement) with increasing field and no tunable response.
