Calculated lattice thermal conductivity of MgSiO3 postperovskite (PPv) and bridgmanite (Brg) under the Earth’s lowermost mantle conditions
13 Feb 2020
Lattice thermal conductivities of MgSiO3 bridgmanite and postperovskite (PPv) phases under the Earth’s deepest mantle conditions were determined by quantum mechanical computer simulations. We found a substantial increase in the conductivity associated with the phase change. This indicates that the PPv phase boundary is the boundary not only of the mineralogy but also the thermal conductivity. The effect of anisotropy on the conductivity of PPv in the heat transport properties at the lowermost mantle was also found to be minor.

Obtained unusual nanostructures
18 Oct 2019
A research team of Ehime University paved a way to achieve unexplored III-V semiconductor nanostructures. They grew branched GaAs nanowires with a nontoxic Bi element employing characteristic structural modifications correlated with metallic droplets, as well as crystalline defects and orientations. The finding provides a rational design concept for the creation of semiconductor nanostructures with the concentration of constituents beyond the fundamental limit, making it potentially applicable to novel efficient near-infrared devices and quantum electronics.

A new type of photoconduction in a molecular crystal
29 Aug 2019
A highly conducting state has been found in a molecular crystal under UV-irradiation. The state reversibly appears in accordance with UV-irradiation, but does not appear by any other method such as raising the temperature, which often induces metallic behavior in insulating molecular crystals. The UV-excited state exhibits conduction and magnetic behavior characteristic of metallic substances. The result suggests that there is an optically accessible, but thermally inaccessible, state of matter.

Japanese scientists have found a new way to successfully detect the efficiency of crystal semiconductors. For the first time ever, the team used a specific kind of photoluminescence spectroscopy, a way to detect light, to characterize the semiconductors. The emitted light energy was used as an indicator of the crystal's quality. This method potentially culminates in more efficient light-emitting diodes (LEDs) and solar cells. Additionally, it could usher in several other advances in electronics.

Phase H is a hydrous mineral that is considered to be an important carrier of water into deep Earth. We determined the dissociation condition of phase H by a theoretical calculation based on quantum mechanics. Phase H decomposes at approximately 60 GPa at 1000 K. This indicates that the transportation of water by phase H may be terminated at a depth of approximately 1,500 km in the middle of the lower mantle.
