HRTEM (unfiltered) micrograph corresponding to the blue square in (b), where a transition from diamond to graphite is shown. White lines mark 111-type diamond planes with spacings of ~2.1 Å, and yellow lines mark both 100- and 001-type graphite-like (graphene) planes with spacings of ~2.1 and ~3.5 Å, respectively. This interfacial region resembles a so-called type 1 “diaphite” phase.(28)
