Query: Epitaxial growth of bilayer Bi(110) on two-dimensional ferromagnetic
  Fe3GeTe2   Heterostructures of two-dimensional (2D) layered materials with selective
compositions play an important role in creating novel functionalities.
Effective interface coupling between 2D ferromagnet and electronic materials
would enable the generation of exotic physical phenomena caused by intrinsic
symmetry breaking and proximity effect at interfaces. Here, epitaxial growth of
bilayer Bi(110) on 2D ferromagnetic Fe3GeTe2 (FGT) with large magnetic
anisotropy has been reported. Bilayer Bi(110) islands are found to extend along
fixed lattice directions of FGT. The six preferred orientations could be
divided into two groups of three-fold symmetry axes with the difference
approximately to 26{\deg}. Moreover, dI/dV measurements confirm the existence
of interface coupling between bilayer Bi(110) and FGT. A variation of the
energy gap at the edges of bilayer Bi(110) is also observed which is modulated
by the interface coupling strengths associated with its buckled atomic
structure. This system provides a good platform for further study of the exotic
electronic properties of epitaxial Bi(110) on 2D ferromagnetic substrate and
promotes potential applications in the field of spin devices.
