- Abstract
- Nanowires have shown great promise in the research field, however, it seems quite a challenge to get them incorporated into the silicon industry and entering the commercial field. One step towards this is to substitute the gold which is used for the catalyst particle for a different material, compatible with the silicon industry. In this project, the possibility of using in-situ nucleation inside of an MOVPE-reactor to form particles
was examined. With tin, seed particles were successfully grown, and it was shown that by varying the growth conditions, both the size and the density of the particles can be controlled. Attempts using zinc, selenium and antimony were unsuccessful, mainly due to high vapour pressures and limitations on...

Attempts using zinc, selenium and antimony were unsuccessful, mainly due to high vapour pressures and limitations on precursor flows. Aluminium showed some promising results with particle formation at temperatures well below the melting point. However, they were lacking in consistency and reproducibility, so to utilize this method with aluminium, further studies are required. (Less)
