An ideal platform

A device platform that uses transferred contacts made from a hexagonal boron nitride layer with embedded metal can create two-dimensional transistors with near-ideal device characteristics. The cover shows an optical microscopy image of a field-effect transistor made from bilayer tungsten diselenide built using the platform.
