We describe one example of such a superlattice, with a lattice constant nearly twice of that of pristine graphene. We performed comprehensive theoretical calculations to investigate the lattice and the electronic structure of the superlattice structure. Our results reveal that it is a thermodynamically stable, spin-polarized semiconductor with a bandgap of similar to 0.5 eV.

Our results demonstrate selleck chemical the possibility of controlling graphene’s electronic properties using aryl diazonium functionalization. Asymmetric addition of aryl groups to different sublattices of graphene is a promising approach for producing ferromagnetic, semiconductive graphene, which Inhibitors,Modulators,Libraries will have broad applications in the electronic industry.”
“Many Inhibitors,Modulators,Libraries technological applications indispensable in our daily lives rely on carbon.

By altering the periodic binding motifs in networks of sp(3), sp(2), and sphybridized carbon atoms, researchers have produced a wide palette of carbon allotropes. Over the past two decades, the physicochemical properties of low-dimensional nanocarbons, including fullerenes (0D), carbon nanotubes (1D), and, Inhibitors,Modulators,Libraries most recently, graphene Inhibitors,Modulators,Libraries (2D), have been explored systematically.

An entire area of research has focused on the chemistry of 1D nanocarbons, particularly single-wall carbon nanotubes. These structures exhibit unique electronic, mechanical, and optical properties. These properties are, however, only discernible for single-wall carbon nanotubes that are debundled, individualized, and stabilized, often in solution.

Most prominently, they are small band gap, p-type semiconductors or metals with conductances that reach ballistic dimensions. Inhibitors,Modulators,Libraries These structures can have poor solubility In many media, and large bundles can originate from attractive interactions such as pi-pi stacking and London dispersion forces. Therefore, both covalent and noncovalent modifications of single-wall carbon nanotubes have emerged as powerful approaches to overcome some of these problems. Noncovalent functionalization is especially useful in improving the solubility without altering the electronic structure.

We expect that many of the strategies that have recently been exploited and established In the context of 1D nanocarbons can be applied to the chemistry of 2D nanocarbons, especially graphene. Two-dimensional nanocarbons are currently attracting extensive attention due to their striking mechanical, optical, and electrical features. Nanocarbons that are a single atom thick are gapless semiconductors and exhibit electron mobilities reaching values of up to 15000 cm(2) V-1 s(-1) at room temperature. Researchers have made rapid progress GSK1210151A 1300031-49-5 in the covalent and/or noncovalent functionalization of graphene with photoactive and or redox active building blocks.
