Witryna1 wrz 2024 · Graphitization is the process which improves lattice order with decrease in interlayer spacing in both graphitizing and non-graphitizing carbons. Some materials attain ordered orientation at 2000 °C (graphitizing), while others do not show homogeneous graphitic (ordered) structure even at 3000 °C (non-graphitizing). WitrynaGraphitized layers as suspended membranes show extraordinary mechanical stability and can be used in various MEMS. Nearly any organic material can be graphitized by ion irradiation. We investigate the relationship between parameters of low-energy ion irradiation and properties of the graphitized surfaces.
