Query: Two-dimensional spinodal interface in one-step grown graphene-molybdenum
  carbide heterostructures   Heterostructures made by stacking different materials on top of each other
are expected to exhibit unusual properties and new phenomena. Interface of the
heterostructures plays a vital role in determining their properties. Here, we
report the observation of a two-dimensional (2D) spinodal interface in
graphene-molybdenum carbide ({\alpha}-Mo2C) heterostructures, which arises from
spinodal decomposition occurring at the heterointerface, by using scanning
tunneling microscopy. Our experiment demonstrates that the 2D spinodal
interface modulates graphene into whispering gallery resonant networks filled
with quasi-bound states of massless Dirac fermions. Moreover, below the
superconducting transition temperature of the underlying {\alpha}-Mo2C, the 2D
spinodal interface behaves as disorders, resulting in the breakdown of the
proximity-induced superconductivity in graphene. Our result sheds new light on
tuning properties of heterostructures based on interface engineering.
