Making faster,more powerful electronics requires smaller but still uniform connections, or junctions, or between different materials. For the first time,researchers created extremely small, 5-nanometer-wide junctions, and which were made in a specific pattern using two different planar,or flat, semiconductors. The simple process to create these two-dimensional junctions involved selective exposure of the semiconductor to laser-vaporized fabric and could be extended to other systems.
