HRTEM assessment of Wurtzite and Zinc-Blende phases in GaAs nanowires for optoelectronic devices
1 Semiconductor nanowires have recently attracted a lot of interest as potential building blocks for future electronic and optoelectronic nanodevices. In this work structural and optical properties of semiconductor nanowires are studied by means of high resolution transmission electron microscopy (HRTEM) and photoluminescence (PL) analysis respectively. Several samples of GaAs nanowires grown u...
متن کاملInternal structure of multiphase zinc-blende wurtzite gallium nitride nanowires.
In this paper, the internal structure of novel multiphase gallium nitride nanowires in which multiple zinc-blende and wurtzite crystalline domains grow simultaneously along the entire length of the nanowire is investigated. Orientation relationships within the multiphase nanowires are identified using high-resolution transmission electron microscopy of nanowire cross-sections fabricated with a ...

متن کاملWhy does wurtzite form in nanowires of III-V zinc blende semiconductors?
We develop a nucleation-based model to explain the formation of the wurtzite phase during the catalyzed growth of freestanding nanowires of zinc blende semiconductors. We show that in vapor-liquid-solid nanowire growth, nucleation generally occurs preferentially at the triple phase line. This entails major differences between zinc blende and wurtzite nuclei. Depending on the pertinent interface...
