15 صفحه اولPhase controlled synthesis of ZnS nanobelts: zinc blende vs wurtzite
Bulk crystals of ZnS usually take the zinc blende structure. However, the vapor deposited one-dimensional ZnS nanostructures normally take the metastable wurtzite structure. This Letter investigates the conditions under which the formed phase can be controlled between zinc blende and wurtzite in nanomaterials synthesis. The formation of pure zinc blende structured ZnS nanobelts is related not o...
متن کاملOptical properties of wurtzite and zinc-blende GaNÕAlN quantum dots
We investigate theoretically and compare optical properties of wurtzite and zinc-blende GaN/AlN quantum dots with heights from 1.5 to 4.5 nm. The quantum dot size corresponds to the strong quantum confinement regime. It has been established that the built-in piezoelectric field at the GaN/AlN interface governs optical properties of wurtzite quantum dots while having a small effect on zinc-blend...
متن کاملBand discontinuities in zinc-blende and wurtzite AlN/SiC heterostructures
The AlN/SiC band discontinuities in zinc-blende ~110!, ~111!, and wurtzite ~0001! heterostructures were examined using the ab initio pseudopotential approach. At the nonpolar AlN/SiC~110! junction, we find a valence-band offset of 1.7 eV. At the polar heterojunctions the band alignment depends on the interface composition, and valence-band offsets as high as 2.5 eV are obtained for neutral inte...
متن کاملDX-center formation in wurtzite and zinc-blende AlxGa12xN
The transition from shallow to deep centers as a function of pressure or alloying is investigated for oxygen and silicon donors in GaN and AlN, based on first-principles total-energy calculations. The stability of the localized deep state (DX center! is found to depend on interactions between the impurity and third-nearestneighbor atoms, which occur in different positions in the zinc-blende and...
