An atomically thin material developed at Rice University may lead to the thinnest-ever imaging platform.
Synthetic two-dimensional materials based on metal chalcogenide compounds could be the basis for superthin devices, according to Rice researchers. One such material, molybdenum disulfide, is being widely studied for its light-detecting properties, but copper indium selenide (CIS) also shows extraordinary promise.
Sidong Lei, a graduate student in the Rice lab of materials scientist Pulickel Ajayan, synthesized CIS, a single-layer matrix of copper, indium and selenium atoms. Lei also built a prototype—a three-pixel, charge-coupled device (CCD)—to prove the material's ability to capture an image.
The details appear this month in the American Chemical Society journal Nano Letters.To read more, click here.
