Nonfiltered HR-STEM micrograph of additional features arising from the laser interaction. An interface region (highlighted by the red squares) is shown in greater detail. FFTs of regions labeled as c2 and c3 indicate the appearance of new reflections consistent with 111 planes of orthorhombic graphite. Evidence of transformation of 111 planes of diamond into 112 or 220 planes of orthorhombic graphite is also observed, as highlighted with dashed lines along the interface. Only partial transformation is realized since diamond reflections are also present in all FFTs.
