Single crystals of the new semiconducting oxytelluride phase, Ba2TeO, were synthesized from barium oxide powder and elemental tellurium in a molten barium metal flux. Ba2TeO crystallizes in tetragonal symmetry with space group P4/nmm (#129), a = 5.0337(1) angstrom, c = 9.9437(4) angstrom, Z = 2. The crystals were characterized by single crystal x-ray diffraction, heat capacity and optical measurements. The optical measurements along with electronic band structure calculations indicate semiconductor behavior with a band gap of 2.93 eV. Lastly, resistivity measurements show that Ba2TeO is highly insulating.
