2. Doping Si nanowires I want to grow Si nanowires with a p-doped and n-doped region within the same Si nanowire via vapor-liquid-solid mechanism using gold nanoparticles as catalyst. For dopants, I want to use boron and phosphorus. How would you do this? Describe your growth process (steps) and conditions. You can refer to class notes and Journal of Physical Chemistry B 104, p.5123 (2000) for inspiration N-doped P-doped
