Abstract

The sp³-bonded "transparent phase" of carbon, formed by compression of single-crystal graphite to 18 GPa, has been found to be quenchable to atmospheric pressure at low temperatures (< 100 K). The quenched transparent phase reverts to graphite upon warming to room temperature, indicating that there is a surprisingly small activation barrier for a transformation that must involve carbon-carbon bond breakage. Visual observations and Raman spectroscopy are used to document the novel ambient pressure transformation.
