    Abstract: Structures and methods for controlling phonon-scattering are provided. In some embodiments, a metamaterial structure comprises a light absorbing layer (16) capable of absorbing solar energy and converting the absorbed energy into electrical current, a first patterned layer (14) disposed on a light absorbing surface of the light absorbing layer (16), the first patterned layer (14) being configured to increase light absorption in the light absorbing layer (16), and a second patterned layer (60) disposed in proximity to the light absorbing layer (16), the second patterned layer (60) being configured to control phonon-scattering by storing or protecting the hot electron energy in the light absorbing layer (16).
