Nanoscale Control of Temperature Distribution Using a Plasmonic Trimer

A plasmonic trimer composed of three closely packed identical gold nanospheres for manipulating nanoscale temperature distribution is proposed. It is shown that heat can be unevenly distributed among the three particles, creating a high temperature gradient in the nanoscale space despite the strong thermalization effect. Moreover, the difference in temperature increment among the particles is sensitive to the polarization of incident light and can be continuously tuned. The dependence of the achievable temperature difference on the trimer parameters is also investigated. The ability of nanoscale selective heating provides a possible way of remotely manipulating the nanoscale thermally induced physical or chemical processes with unprecedented spatial precision.
