WebWO3 has a basic octahedron structure. From -140 ∼ 830°C, the crystal structure changes from monoclinic to triclinic, again monoclicnic, then successively orthorhombic, tetragonal, and again tetragonal. Several groups have investigated the electronic structure of WO3 within DFT, but the band gap is severely underestimated compared with ... WebIn ccp, they are staggered. hcp ccp Another difference arises from the packing order. In the hcp, there are never any atoms over the "right-pointing" holes. Thus, if we look directly down on the structure we can …
