The use of ultrathin 2D semiconductor materials promises to shrink transistors down to the nanometer scale. However, to achieve a substantial increase in the number of these transistors that can fit on a chip, it is necessary to reduce the metal contacts that connect them to external circuitry. Until now, it has been unclear how
