Adding extra material on top of a sheet of silicon could, surprisingly, reduce its ability to transport heat, according to simulations, and this property could benefit future refrigeration or energy-generating devices.

Researchers measured the interaction between surface plasmons–electron waves on metal surfaces–with excitons, excited states of electrons in semiconductors. Understanding the communication between the two could improve solar cells and speed up electronic and optical devices.
