Changing a 2D material’s symmetry can unlock its
promise

Optoelectronic materials that are capable of
converting the energy of light into electricity, and electricity
into light, have promising applications as light-emitting,
energy-harvesting, and sensing technologies. However, devices made
of these materials are often plagued by inefficiency, losing
significant useful energy as heat. To break the current limits of
efficiency, new principles of light-electricity conversion are
needed.
