Graphite stripes are deposited onto silicon with industry-standard lithography to obtain a densely-packed memory.
When a current is applied, the graphite layer breaks (b). Another jolt restores the stripe completely (a).
Details of the graphite-based vias.
Graphite has long been known to have unique electrical properties and has therefore been put forward by many as a possible substitute for silicon for use in integrated circuitry. Now, in a major step towards making graphene-based electronics, researchers from Rice University have published the results of work on graphite-based mass data storage and reprogrammable gate arrays.
