ORNL researchers make scalable arrays of ‘building blocks’ for ultrathin electronics

For the first time, researchers at the Department of Energy’s Oak Ridge National Laboratory have combined a novel synthesis process with commercial electron-beam lithography techniques to produce arrays of semiconductor junctions in arbitrary patterns within a single, nanometer-thick semiconductor crystal. The process transforms patterned regions of one existing, single-layer crystal into another. The two semiconductor crystals formed sharp junctions, the desired building blocks of electronics. Nature Communications reports the accomplishment. —> Read More
