Diamond-based circuits can take the heat for advanced applications

10.04. 2018 Condensed Matter News - Physics News, Physic Materials News, Physics, Materials

When power generators like windmills and solar panels transfer electricity to homes, businesses and the power grid, they lose almost 10 percent of the generated power. To address this problem, scientists are researching new diamond semiconductor circuits to make power conversion systems more efficient.

Researchers from TU Delft, Cornell University and the University of Cagliari report an interesting method for turning a highly insulating material into a highly conducting system. The process involves combining three different metal oxides in a sharp interface. They have recently published their findings in ACS Applied Materials & Interfaces.

‘Brazil nut effect’ helps explain how rivers resist erosion, team finds

Pop the top off a can of mixed nuts and, chances are, Brazil nuts will be at the top. This phenomenon, of large particles tending to rise to the top of mixtures while small particles tend to sink down, is popularly known as the "Brazil nut effect" and more technically as granular segregation.

Missing link between new topological phases of matter discovered

18.10. 2017 Condensed Matter News - Physics News, Physic Materials News, Physics, Materials

Physicists at BESSY II have investigated a class of materials that exhibit characteristics of topological insulators. During these studies, they discovered a transition between two different topological phases, one of which is ferroelectric, meaning a phase in the material that exhibits spontaneous electric polarisation and can be reversed by an external electric field. This could also lead to new applications such as switching between differing conductivities.

Uncovering the connection between negative stiffness and magnetic domain walls

14.07. 2017 Condensed Matter News - Physics News, Physic Materials News, Physics, Materials

Nature doesn't like having interfaces—this is why bubbles like to be round, and the surface of a pond settles to flat as long as it's not disturbed. These trends minimize the total amount of interface (or surface) that is present. As an exception to this behavior, certain materials are known to have a property, called negative stiffness, where the interface prefers to become distorted, or wavy, even without any external stimulation.
