Changyeong Jeong, a graduate student in electrical engineering and computer science, measures how well light passes through a sheet of flexible transparent conductor. The material sandwiches a thin layer of silver between two “dielectric” materials, aluminum oxide and zinc oxide, producing a conductive anti-reflection coating on the sheet of plastic.
