Formation mechanisms of embedded wurtzite and zincblende indium nitride nanocrystals

Formation mechanisms of spatially-directed zincblende gallium nitride nanocrystals

Solvothermal synthesis of zincblende and wurtzite CuInS2 nanocrystals and their photovoltaic application.

We report a simple solvothermal synthesis approach to the growth of CuInS(2) nanocrystals with zincblende- and wurtzite-phase structures. Zincblende nanocrystals with particle sizes of 10-20 nm were produced using oleylamine as the solvent. When ethylenediamine was used as the solvent, similarly sized wurtzite nanocrystals with some degree of particle aggregation were formed. Use of a mixture o...

Formation mechanisms of spatially-directed zincblende gallium nitride nanocrystals Role of oxygen on microstructure and thermoelectric properties of silicon nanocomposites Spectrally and temporarily resolved luminescence study of short-range order in nanostructured amorphous ZrO2 Characterization of luminescent silicon carbide nanocrystals prepared by reactive bonding and subsequent wet chemica...

Ambient pressure, low-temperature synthesis and characterization of colloidal InN nanocrystals.

Highly soluble, non-aggregated colloidal wurtzite InN nanocrystals were obtained through an ambient pressure, low-temperature method followed by post-synthesis treatment with nitric acid.

Polar optical phonons in wurtzite spheroidal quantum dots: theory and application to ZnO and ZnO/MgZnO nanostructures

Polar optical-phonon modes are derived analytically for spheroidal quantum dots with wurtzite crystal structure. The developed theory is applied to freestanding spheroidal ZnO quantum dots and to spheroidal ZnO quantum dots embedded into a MgZnO crystal. The wurtzite (anisotropic) quantum dots are shown to have strongly different polar optical-phonon modes in comparison with zincblende (isotrop...
