AI Article Synopsis
- A new method for preparing CdTe nanowires produces structures with a high aspect ratio and mainly a metastable wurtzite phase.
- The optical and morphological features of these nanowires were analyzed, along with how increased temperatures affect their crystallographic properties.
- A phase transition from wurtzite to sphalerite occurs around 500°C, indicating that the synthetic method and surfactants help stabilize the wurtzite phase.
Article Abstract
A new organometallic preparation method is described for CdTe nanowires with a high aspect ratio and a predominantly metastable wurtzite phase. The optical and morphological properties of the resulting nanowires were studied, as well as the influence of elevated temperatures on the crystallographic properties. A phase transition from wurtzite to sphalerite was observed at about 500 degrees C. The results show that the wurtzite phase is stabilized by the synthetic method and the surfactants.
