Three atom-thick electronic sheets
Cornell scientists have demonstrated a way to create a new kind of semiconductor thin film that retains its electrical properties even when it is just atoms thick.
Three atom-thick layers of molybdenum disulfide were cooked up in the lab of Jiwoong Park, associate professor of chemistry and chemical biology and member of the Kavli Institute at Cornell for Nanoscale Science. “The electrical performance of our materials was comparable to that of reported results from single crystals of molybdenum disulfide, but instead of a tiny crystal, here we have a 4-inch wafer,” Park said.
The researchers envision perfecting the process to make atomically thin films of all varieties, like a packet of colored paper, from which new, exciting electronic and optoelectronic devices can be derived.
