Chemical transport phenomena in the ZnO–Ga2O3 system

An interrogation of the zinc oxide–gallium oxide phase space by plasma enhanced chemical vapor deposition

“…It is a line compound with minimal solubility with either ZnO or Ga 2 O 3 . High temperature synthesis using either solid state [32] or vapor transport [34] techniques results in two phase systems when deviations from the 1:2 stoichiometry are used. In the case of PECVD, there appears to be a relatively large window for zinc gallate synthesis.…”

Gallia–ZnO nanohybrid sensors with dramatically higher sensitivity to ethanol in presence of CO, methane and VOCs

“…whereas O atoms are located at (u,u,u) position where u indicates the internal parameter [45][46][47]. ZnO and the ZnGa 2 O 4 may have formed according to the following equations:…”

Microwave‐Hydrothermal Synthesis of Nanostructured Zinc‐Copper Gallates

“…[21] The properties of zinc gallates in general are a function of their preparation and of the resulting morphology, such as nanowires, [12,22,23] polyhedron-related, rod-like or irregular shapes. [24] The prevailing synthetic approaches to pristine and substituted ZnGa 2 O 4 materials are solid-state reactions, [5,7,13,20,[25][26][27] sol-gel methods, [18,28,29] pulsed laser deposition techniques, [30] co-precipitation, [7] chemical transport, [31] thermal evaporation, [12,22,23,32] the Pecchini approach [19] and hydrothermal methods [24,26,27,[33][34][35][36][37] (for a survey see Supporting Information, Table S.1). Among these techniques, hydrothermal syntheses are of special interest, because they can provide homogeneous phases and particle size distributions as well as tuneable particle morphologies in a single reaction step.…”
