A new method of synthesising nanoparticle-functionalised nanostructured materials via Aerosol Assisted Chemical Vapour Deposition (AACVD) has been developed. Co-deposition of Au nanoparticles with WO(3) nanoneedles has been used to deposit a sensing layer directly onto gas sensor substrates providing devices with a six-fold increase in response to low concentrations of a test analyte (ethanol).
Field-effect transistor biomolecular sensors based on low-dimensional nanomaterials boast sensitivity, label-free operation and chip-scale construction. Chemical vapour deposition graphene is especially well suited for multiplexed electronic DNA array applications, since its large two-dimensional morphology readily lends itself to top-down fabrication of transistor arrays. Nonetheless, graphene...
This commmunication presents a study of atomic layer deposition of Al2O3 on transition metal dichalcogenide (TMD) two-dimensional films which is crucial for use of these promising materials for electronic applications. Deposition of Al2O3 on pristine chemical vapour deposited MoS2 and WS2 crystals is demonstrated. This deposition is dependent on the number of TMD layers as there is no depositio...
A hybrid approach of colloidal lithography and metalorganic chemical vapour deposition (MOCVD) has been used to fabricate ZnO nanowire bundles and nanoholes by using a silver metalorganic precursor as the growth catalyst.
The rapid thermal direct deposition of micro-crystalline silicon (μc-Si) layers by atmospheric pressure chemical vapour deposition (APCVD) can be done on different intermediate layers and on various substrates. The deposition is done at temperatures between 850 °C and 1150 °C. A deposition rate of 1.6 μm/min has been achieved using standard process conditions. The microcrystalline structure cha...
Here, we report the synthesis of semiconducting single-walled carbon nanotubes with a narrow diameter distribution between 0.67 and 1.1 nm via chemical vapour deposition on graphene layers using Pt catalysts.
