A novel graphene quantum dot structure takes the cake

In a marriage of quantum science and solid-state physics, researchers at the National Institute of Standards and Technology (NIST) have used magnetic fields to confine groups of electrons to a series of concentric rings within ...

Twisted electronics open the door to tunable 2-D materials

Two-dimensional (2-D) materials such as graphene have unique electronic, magnetic, optical, and mechanical properties that promise to drive innovation in areas from electronics to energy to materials to medicine. Columbia ...

Research shows graphene forms electrically charged crinkles

Researchers from Brown University have discovered another peculiar and potentially useful property of graphene, one-atom-thick sheets of carbon, that could be useful in guiding nanoscale self-assembly or in analyzing DNA ...

Evidence found of magnetism at the edges of graphene

A team of researchers from the U.K., Germany and Russia has found evidence of magnetism at the edges of graphene. In their paper published in the journal Nature, the researchers describe how they made their discovery and ...

Researchers squeeze light into nanoscale devices and circuits

As electronic devices and circuits shrink into the nanoscale, the ability to transfer data on a chip, at low power with little energy loss, is becoming a critical challenge. Over the past decade, squeezing light into tiny ...

Researchers operate lab-grown heart cells by remote control

Researchers at University of California San Diego School of Medicine and their collaborators have developed a technique that allows them to speed up or slow down human heart cells growing in a dish on command—simply by ...
