Ultrathin Bi 2 S 3 nanowires undergo a pronounced photothermal response to irradiation from a commercial camera flash. Controlled nano‐welding was shown by using single walled carbon nanotube mats as an electrically and thermally conductive substrate. The resulting welded nanowire film is denser and has significantly lower resistance than unflashed bilayer films.
