A wafer-thin flake of bismuth telluride can act a little like a one-way street for electricity, even when the push comes from ...

In most conventional semiconductors, thermal conductivity decreases as temperature rises because heat-carrying lattice vibrations—called phonons—scatter more frequently.

Researchers have captured the first direct, momentum-resolved evidence that certain lattice vibrations carry measurable ...

Scientists have decoded how heat flows in magnetic semiconductors, materials that are critical to emerging technologies such as spintronics, magnetic memory, and quantum devices. The discovery ...

By influencing how phonons travel through a crystal lattice, an electric field can begin shaping both the speed and direction of heat transport.

Flying at hypersonic speeds — defined as Mach 5 and above — is likely the toughest environment to engineer materials for. At these speeds, temperatures can reach beyond (1,727° C), straining even the ...

Scientists in the United States have discovered an electric field method to improve heat ...

An international team of researchers has shown that superconductivity can be modified by coupling a superconductor to a dark electromagnetic cavity. The research opens the door to the control of a ...

Physicists in China have uncovered new evidence that chiral phonons and magnons can interact strongly inside magnetic crystals. Using neutron spectroscopy, a team led by Song Bao at Nanjing University ...

New research from the Department of Energy's Oak Ridge National Laboratory, in collaboration with The Ohio State University and Amphenol Corporation, challenges conventional understanding about ...

The company is seeking F.C.C. approval to test an idea to reflect sunlight to Earth at night, possibly powering solar panels. Critics say it could be bad for people and wildlife.

A team of researchers from Boston College has created a new metallic specimen where the motion of electrons flows in the same way water flows in a pipe—fundamentally changing from particle-like to ...
