Chemical nature of boron and nitrogen dopant atoms …

The doped graphenes can be prepared by a broad variety of chemical approaches. The substitution of a carbon atom should induce n-type behavior in the case of nitrogen and p-type behavior in the case of boron-doped graphene; however, the real situation is more complex.

Metal-Free Synthesis of Boron-Doped Graphene Glass …

2020-1-15 · Property modulation of graphene glass by heteroatom doping such as boron (B) and nitrogen (N) is important to extend its practical applications. However, unlike N doping, research studies about the metal-free synthesis of B-doped graphene on glass through the chemical vapor deposition (CVD) method are rarely reported.

Interlayer Coupling Behaviors of Boron Doped …

Here we investigate the interlayer coupling of multilayer graphene doped with controlled boron content via the Raman-active in-plane shear mode. The experimental results reveal a remarkable decline in the interlayer shear modulus as boron content increases, which is a direct consequence of the enlarged interlayer spacing, further supported by ...

Synthesis and Applications of Semiconducting Graphene

Influence of codoping of graphene with two or more atoms is also observed in different studies. For example, another experiment showed that an electrode based on B and N codoped graphene resulted in capacitance way higher compared to counterpart electrodes of pristine graphene or only boron-doped graphene or only nitrogen-doped graphene.
