Carbon‐assisted thermal coevaporation of In 2 O 3 and GeO 2 generates monocrystalline, sub‐micrometer In 2 Ge 2 O 7 tubes with a laminar crystal structure (see figure). Within an In 2 Ge 2 O 7 tube, the {InO 6 } 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.
