ABSTRACT
Scientists could make better chemical weapon detectors, improve airport scanners and see distant galaxies by tricking 1-millimeter-thick sheets of carbon called graphene. Univ. of Maryland researchers used the ultrasensitive material for a bolometer, a type of infrared light detector used in sensing equipment. Usually bolometers are made with silicon or other semiconductors, which work in different temperature ranges than graphene. By exposing the carbon to an electrical charge, researchers coaxed out the right properties at the needed temperatures.
