Experimentally, with respect to the (002) peak in benzenoid materials, not all aromatic carbons need contribute to an intermolecular interference peak, so that determinations of sp2 or sp3 carbon abundance based
Carbon is a versatile element that has allotropes with both sp2 (graphene) and sp3 (diamond) bonding. However, none of the allotropes can be used as light-absorber materials in solar cells due to either too large or too small band gap. Here, we propose a novel concept that enables a ...
对于碳系吸波剂的研究通常集中在以石墨烯及碳纳米管为代表的sp2杂化碳材料,而很少考虑sp3杂化碳材料,其中一个很重要的原因是sp3杂化的碳材料在热力学及合成方法上相较于sp2杂化碳更难制备。而考虑到sp3碳与sp2碳在电负性上的天然差异,构造一种含有丰富的sp2-sp3 C-C极性共价键的碳材料能够引入强烈的偶极子极化行...
The results indicate that this nc-graphite is in Stage-2 of Ferrari's amorphization trajectory between amorphous carbon (a-C) and graphite with a sp2/sp3 carbon ratio of 85/15. The nano-crystallites size of 1.5 nm from XRD is consistent with fast HET rates as this increases the ...
Carbon, sp2‐hybridizedCarbon, sp3‐hybridizedLithographyPatterning, laser‐inducedA new method of laser-induced lithography for direct writing of carbon on a glass surface is described, in which deposition occurs from a transparent precursor solution. At the glass–solution interface where the laser ...
