a The atomic geometries of 1D face-sharing octahedral frameworks of Peierls-distorted GeCl3, and Peierls distortion-avoiding GeI3, and SnI3 inorganic nanowires. b The electronic band spectra showing the semiconducting character of GeCl3 and semimetallic nature of GeI3 and SnI3 nanowires. For GeI3, in addition to the PBEsol band structure (black solid lines), HSE data are presented (red dotted lines). c Phonon band spectra (left panels) and corresponding vibrational DOS (VDOS; right panels) of GeI3 and SnI3 nanowires. For the vibrational DOS, we show the projections to Ge or Sn (red lines), and I (green lines)
