Damaging graphene to create a band gap

(PhysOrg.com) -- "Graphene offers a lot of interesting potential applications for nanoelectronics," Florian Banhart tells PhysOrg.com, "but there is no band gap. This is a well-known problem. Without the band gap, switching ...

Novel method for easier scaling of quantum devices

In an advance that may help researchers scale up quantum devices, an MIT team has developed a method to "recruit" neighboring quantum bits made of nanoscale defects in diamond, so that instead of causing disruptions they ...

Simulations show how to turn graphene's defects into assets

Researchers at Penn State, the Department of Energy's Oak Ridge National Laboratory and Lockheed Martin Space Systems Company have developed methods to control defects in two-dimensional materials, such as graphene, that ...

Charged holes in graphene increase energy storage capacity

Engineers at the University of California, San Diego have discovered a method to increase the amount of electric charge that can be stored in graphene, a two-dimensional form of carbon. The research, published recently online ...

Phosphorus a promising semiconductor

(Phys.org) —Defects damage the ideal properties of many two-dimensional materials, like carbon-based graphene. Phosphorus just shrugs.

Observing the random diffusion of missing atoms in graphene

Imperfections in the regular atomic arrangements in crystals determine many of the properties of a material, and their diffusion is behind many microstructural changes in solids. However, imaging non-repeating atomic arrangements ...

Flawed diamonds: Gems for new technology

(Phys.org) —Using ultra-fast laser pulses, a team of researchers led by UA assistant professor Vanessa Huxter has made the first detailed observation of how energy travels through diamonds containing nitrogen-vacancy centers ...
