Multifunctional nanomaterials and nanoelectronic devices based on nitrides, oxides and chalcogenides for biomedicine / Nanomateriale multifuncţionale şi dispozitive nanoelectronice în bază de nitruri, oxizi şi calcogenuri pentru biomedicină | Conference: | NANO-2019: Limits of Nanoscience and Nanotechnologies | Abstract: | The present investigation is devoted to obtaining ZnO, In2O3 and Ga2O3 single crystals by chemical vapor transport (CVT). The thermodynamic analysis of the composition of CVT systems with ZnO, In2O3, Ga2O3 and various transport agents (TAs) is carried out for wide temperature range and for various density/composition of TA. The influence of the growth temperature and of the TA density/composition on the mass transport rate is investigated theoretically and experimentally. The possibility of increase in mass transport rate by several orders of magnitude at the presence of compound TAs is demonstrated. The application prospects of obtained single crystals as substrates for manufacturing nanoporous matrices (nanotemplates) by the electrochemical etching are analyzed. The fabrication of nanopore arrays with various morphology, which depends on the crystallographic orientation of substrates, is demonstrated for ZnO. |
