Scientists at PNNL study how to use nano-structured chalcogenides for sensing of harmful chemicals in the environment. This image shows amorphous selenium microstructures on fused quartz that was grown through a unique vapor deposition process in a temperature gradient under vacuum. Materials such as these are a suitable candidate for chemical sensing applications due to their optical transparency in the infrared.
