• photonic circuits, and solar cells [1][2][3]. Semiconductor nanowires have been a topic of intense research in the scope of third generation photovoltaic technology, with a predicted significant reduction of cost production [4]. Group III–V semiconductor nanowires are considered very promising materials

• greenhouse gases that pollute the environment. Photovoltaic technology is a potentially viable solution to produce clean energy; however, its production costs are still too high due to the materials and process techniques involved. Moreover, because the sun is an intermittent energy source, the further
