The chiral tetragonal phase of elemental tellurium as a result of multiple charge order. (a) The distortion pattern of a one-dimensional chain with a two-third filled band, described by the displacements , with . (b) The same one-dimensional pattern repeated throughout a three-dimensional simple cubic lattice. The displacements are given by , with and . (c) The chiral combination of three differently polarized one-dimensional patterns with a relative phase difference of . The distortion pattern coincides with the tetragonal lattice structure of . The chirality of the pattern is indicated by the corkscrewlike arrow following the double bonds in the final structure.
