When Semiconductors Stick Together, Materials Go Quantum

A team of researchers led by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has developed a simple method that could turn ordinary semiconducting materials into quantum machines – superthin devices marked by extraordinary electronic behavior. Such an advancement could help to revolutionize a number of industries aiming for energy-efficient electronic systems – and provide a platform for exotic new physics.

Using Carbon to Control the Light

Feng Wang is studying how electrical fields modulate the optical properties of a number of materials. The flip of a light switch – a nano-scale light switch – may some day dramatically boost the speed of data transmission, from streaming movies to accelerating the most data-intense computation.

Graphene optical modulators could lead to ultrafast communications

UC Berkeley researchers have shown that graphene, a one-atom-thick layer of crystallized carbon, can be tuned electrically to modify the amount of photons absorbed. This ability to switch light on and off is the fundamental characteristic of a network modulator, opening the door to optical computing in handheld electronics.

Berkeley Lab Scientists Control Light Scattering in Graphene

Scientists at Berkeley Lab and UC Berkeley have learned to control the quantum pathways that determine how light scatters in graphene. As a sheet of carbon just a single atom thick, graphene’s extraordinary crystalline structure gives rise to unique electronic and optical properties. Controlling light scattering not only provides a new tool for studying graphene but points to practical applications for managing light and electronic states in graphene nanodevices.
