dc.description.abstract | Several metastable polymorphs, diverse crystal structures with the same chemical formula, could be accessed through epitaxial interfaces with low energy between epitaxial film and symmetry-matched substrates. Here, we fabricated tungsten oxide (WO3) nanoscaffolds composed of hexagonal WO3 (h-WO3)/monoclinic WO3 (m-WO3) polymorphs, and modulated the proportions of these phases by tuning the W arrival rate during epitaxial growth. The WO3 nanoscaffold is vertically aligned with coherent interphase boundaries between h-WO3 and m-WO3; this structure leads to the persistence of h-WO3 despite its metastable characteristic. The coherent interphase boundaries give rise to the unexpected six-fold m-WO3 phases and a distinct lattice response with intercalated hydrogen defects. This WO3 nanoscaffold with different fractions of two polymorphs would be a good model system to systematically study intercalation chemistry and its application with WO3 polymorphs. | - |
