- and geometric properties of wurtzite CdTe nanowires in the [0001] growth direction containing surface atoms with one dangling bond over a range of cross-sectional topologies and diameters. Consistent with our prior work on CdSe nanowires, we find that CdTe nanowires with hexagonal cross-sections are more stable and possess a larger band

- Sep 01, 2003 · More recently however, our group and others have reported complex ordering in the nitrides along the [0001] growth direction, with periodicities of several wurtzite unit cells , . This differs qualitatively from the 1×1 ordering observed previously, which does not alter the fundamental structural repeat distance along the c-direction.Cited by: 13

- Details of the chemical mechanism underlying the growth of colloidal semiconductor nanocrystals remain poorly understood. To provide insight into the subject, we have preformed a comprehensive study of the polar (0001) and (0001) and nonpolar (1120) wurtzite CdSe surfaces that are exposed during crystal growth using first-principles density functional theory (DFT-GGA) calculations.Cited by: 74

- Hexagonal wurtzite (WZ) GaN is the most thermodynamically stable crystal structure of GaN and the basal c-plane (0001) is the most commonly used crystal orientation, as it is easily grown on (0001) sapphire or (0001) SiC. Each group-III atom is tetrahedrally coordinated to four nitrogen atoms, arranged in an ABABAB stacking sequence, where A and B refer to Ga–N atomic bilayers.

- growth is in the [011] direction for the zinc-blende phase and in the [21¯10¯ ]direction for the wurtzite phase, as determined by selected area electron diffraction (SAED) patterns, not shown. The sharp interface is identified as (111) zinc-blende/(0001) wurtzite, is a totally coherent interface, and extends the entire length of the nanowire.

- Jul 23, 1999 · The influence of both the buffer layer and of substrate nitridation on the polarity of wurtzite {0001} GaN films deposited by two-step metal organic chemical vapor deposition (MOCVD) has been investigated. The polarity of the buffer layer on a nitrided sapphire substrate was altered by varying its thickness or the annealing time.
