Selective production of carbon structures by non‐equilibrium techniques

Communication: Specific carbon structures, including diamond, can be selectively generated by CVD on the same substrate by controlling substrate surface preparation. This results from the use of process conditions far from equilibrium with a kinetic balance between the relative rates of competing mechanisms. The Figure shows the very different RHEED patterns obtained for two well‐defined regions of the same substrate that have received different pre‐treatments. magnified image
