Research abstract
THIS PROGRAM IS TO DEVELOP A NOVEL THERMAL CONTROL COATING WHICH WOULD ALLOW THE EMITTANCE TO BE CONTROLLED BY APPLYING A DC VOLTAGE. THE FOUR-LAYER COATING IS INTENDED FOR INTERNAL OR EXTERNAL METALLIC SPACECRAFT SURFACES. THE COATING WOULD CONSUME NO POWER AND WOULD BE DURABLE IN SPACE. THE ACTIVE LAYER IN THE COATING IS A SEMICONDUCTOR MATERIAL NORMALLY TRANSPARENT IN THE INFRARED. HIGH INFRARED REFLECTIVITY IS ACHIEVED BY INCREASES IN FREE CARRIER DENSITY AT THE SEMICONDUCTOR LAYER'S SURFACE. THIS SURFACE IS SEPARATED FROM THE METAL SUBSTRATE BY AN INSULATOR, ACROSS WHICH THE APPLIED VOLTAGE APPEARS.
