Heterojunction model for Focal Plane Array detector devices

Night vision systems for military and commercial applications usually use an Infrared Focal Plane Array (IRFPA) for its radiation detector. Existing IRFPA models lack simplicity for setting up the detector's architecture/structure and lack continuity between IR detector material, IR detector processes and detector architecture. This paper will discuss the first version a new IRFPA computer model which is to be used to simulate heterojunction IRFPAs with enhanced quantitative and visual information that allow the device engineer to access the impact of material quality, processing procedures and IR detector architecture on IRFPA performance. This new model will be combined with statistical simulation to enable IRFPA design which have high performance and lowest cost.
