Facet controllable synthesis of two-dimensional rare earth oxides

Since graphene was awarded the Nobel Prize in 2010, two-dimensional (2D) materials have continued to attract researchers' attention in logic, storage, optoelectronic and photonic 2D device manufacturing fields because of the atomic thickness and excellent performance. Based on the research of graphene, scientists have discovered some other 2D materials, such as layered transition metal dichalcogenides (TMDs), hexagonal boron nitride (h-BN), and non-layered III–V group semiconductors.
