Recently, the mono layered structure "graphene" is studied
extensively. In graphite the link between layers is by "Van Der Waals
Force" which is weaker than the ionic or covalent bond. So using scraping
method, people can get graphene. However, for other compounds( AlN, BC2N,
GaN, ZnO,......), in which the connection between layers are ionic bonds,
the graphite-like structure have not been got in experiments. My questions
are as follows:
1, Is it possible to get the mono layered compounds( AlN, BC2N, GaN,
2, From the theoretical interests, how to study the stability of mono
layered compounds by first-principles calculation?
Any suggestion or comment is appreciated ! Thank you in advance.
