  Two-dimensional honeycomb crystals have inspired intense research interest
for their novel properties and great potential in electronics and
optoelectronics. Here, through molecular beam epitaxy on SrTiO3(001), we report
successful epitaxial growth of metal-rich chalcogenide Fe2Te, a
honeycomb-structured film that has no direct bulk analogue, under Te-limited
growth conditions. The structural morphology and electronic properties of Fe2Te
are explored with scanning tunneling microscopy and angle resolved
photoemission spectroscopy, which reveal electronic bands cross the Fermi level
and nearly flat bands. Moreover, we find a weak interfacial interaction between
Fe2Te and the underlying substrates, paving a newly developed alternative
avenue for honeycomb-based electronic devices.
