Abstract
An improvement of the design of Schottky barrier infrared detector (SBIR) arrays, as taught by Roosild, et al. We describe modifications of the detector unit cell design which maximize the fraction of detector electrode area exhibiting full spectral emission response. In particular we recommend changes in the impurity density profile, or 'doping', under the Schottky electrode. The new detector cell design can result in a two-fold increase in the photoemission of SBIR arrays, which have small detector cell dimensions.
