Hollow and Polygonous Microtubes of Monocrystalline Indium Germanate

Carbon‐assisted thermal coevaporation of In2O3 and GeO2 generates monocrystalline, sub‐micrometer In2Ge2O7 tubes with a laminar crystal structure (see figure). Within an In2Ge2O7 tube, the {InO6} octahedron laminae are parallel to the [100] growth direction. These structures may find applications in...

Description
Summary:Carbon‐assisted thermal coevaporation of In2O3 and GeO2 generates monocrystalline, sub‐micrometer In2Ge2O7 tubes with a laminar crystal structure (see figure). Within an In2Ge2O7 tube, the {InO6} octahedron laminae are parallel to the [100] growth direction. These structures may find applications in waveguides or microlasers since their diameters are close to the wavelength and mean free path of appropriate photons.
