An Innovative Pattern: Scientists Rewrite Rules for 2D Electronics

By Theresa Duque

A research team led by Alex Zettl, senior faculty scientist in Berkeley Lab’s Materials Sciences Division and professor of physics at UC Berkeley, has developed a new technique for fabricating tiny circuits from ultrathin materials for next-generation electronics, such as rewritable, low-power memory circuits. Their findings were reported in the journal Nature Electronics.

Using the nanofabrication facility at the Molecular Foundry, the researchers prepared two different 2D devices known as van der Waals heterostructures: one by sandwiching graphene between two layers of boron nitride; and another by sandwiching molybdenum disulfide.

When applying a fine electron beam to the boron-nitride “sandwiches,” the researchers demonstrated that they can “write” nanoscale conducting channels, or nanocircuits,
