Nanowires measure just 5–100 nm in diameter and have the ability to transform the technology around people. In the regular process used for developing nanowires, extremely small holes are made in silicon monoxide and these are subsequently filled with a nanodrop of liquid gallium. When this substance comes into contact with arsenic, it solidifies. However, this process causes the substance to become hard at the nanoholes’ corners, which implies that it is not possible to predict the angle at which the nanowires will grow. Researchers were looking for a method to develop uniform nanowires and regulate their position.
