Nanotechnology Energizing Our Future

Highlights

Scientists used a new method to create 3D metallic and semiconductor nanostructures. The scale bar represents one micrometer. The graphics show how the researchers combined multiple techniques to layer materials on top of a 3D DNA framework "scaffolding."

Building 3D Nanoscale Structures Through DNA-Assembly and Templating

Using DNA scaffolding, scientists developed a universal method for producing a wide variety of functional, 3D metallic and semiconductor nanostructures

A spin-LED stack consisting of a chiral semiconductor layer that controls the orientation of electron spins to emit circularly polarized light.

Gaining Control of Spin in Optoelectronics

By combining a chiral semiconductor with an LED, scientists controlled the orientation of electron spin.
