Sandwich-style construction: Toward ultra-low-energy exciton electronics

A new 'sandwich-style' fabrication process placing a semiconductor only one atom thin between two mirrors has allowed Australian researchers to make a significant step towards ultra-low energy electronics based on the light-matter hybrid particles exciton-polaritons. The breakthrough evidence of robust, dissipationless propagation of exciton-polaritons, coupled excitons in atomically-thin material to light, demonstrating for the first time long-range propagation without lost dissipation of energy, at room temperature.
