1
IndependentBNgraphene-like layer
1. A method, comprising: providing a crystalline cubic boron-nitrid e substrate with a diamond-type lattice and an exposed substantially (1 11)-surface; and growing feming a graphene-like layer on the exposed substantially (111)-surface.
1. 2
  Dependent← claim 1BNgraphene-like layer
  The method of claim 1, wherein the (1 1)-surface has lateral lattice constants that match those of lattice constants of the graphene-like layer to, at least, about 3 percent.
2. 3
  Dependent← claim 1BNgraphene-like layer
  The method of claim 1, wherein the substrate-includec diugrowing step includes epitaxially growing the graphene- like layer.
