(color online) (a) OM image of Mo₂C/graphene heterostructure. (b) Raman spectra of A and B, respectively. (c) Optical image and (d) typical EDS image spectrum of Mo₂C crystal fabricated by using CVD under the following condition: 1-sccm CH₄, 200-sccm H₂, 1000-sccm Ar, 40 min, and 100-μm Cu above 100-μm Mo. (e) HRTEM image and (f) SAED pattern of Mo₂C crystal. The inset in panel (d) shows the corresponding Mo₂C crystal (the same as those shown in panel (c)), and the red spot shows the position where the EDS spectrum is acquired.
