Holey cnt synthesis
Nettet29. nov. 2016 · The rate of CNT synthesis can be high, producing around 20–100 mg/min . The rate of synthesis has been shown to increase with increasing gas pressure. Although higher currents during the arc would be expected to produce more material, it has been shown that the deposit becomes fused at higher current, actually reducing the … Nettet10. mar. 2024 · This paper studies holey graphene with various neck widths (the smallest distance between two neighbor holes). For the considered structures, the energy gap, the Fermi level, the density of electronic states, and the distribution of the local density of electronic states (LDOS) were found. The electroconductive properties of holey …
