a Top and side views of the MoTe2 crystal structure. The black rhombus shows the periodicity of the hexagonal hollow sites of the MoTe2 lattice. The black arrows mark the spacing of MoTe2 (\(\bar{1}\)100) planes. b Top view of the energy landscape of Te atoms on MoTe2. The system energy for Te adsorption was obtained by comparing the total energies of MoTe2 with a single Te adatom placed at different surface sites. The white rhombus shows the periodicity of the hexagonal hollow sites, i.e., the lowest energy positions, of the MoTe2 lattice. c Crystal structure of m-Te in a three-dimensional manner (left) and along [100] direction (right). The black rhombus and arrows show the periodicity of Te atoms and the spacing of (021) planes. d Schematic drawing of the bilayer MoTe2 transistor structure using m-Te as p-type contacts. Blue and coral spheres: Te and Mo atoms.
