The material properties, which arise from holes in an impurity band, created by manganese doping, depletes the valence band and shifts the Fermi level . This should enable a boost in the materials' spintronics performance
When laser light impacts a gallium arsenide nanomembrane, some of the light is reflected and the light is reflected back again via a mirror. The light flies back and forth in this space and forms an optical resonator.
Removing gallium from III-V type-II superlattice materials delivers a massive hike in minority carrier lifetime. Thanks to this, these superlattice detectors have the potential to start challenging expensive state-of-the-art HgCdTe infrared imagers
Scientists say they have developed a solar paint which can be made cheaply and in large quantities. If the efficiency can be improved, they may be able to make a real difference in meeting energy needs in the future
The "MacEtch" wet etch solution ensures that only the areas touching metal are etched away, and high-aspect-ratio structures are formed as the metal sinks into the wafer. After etching , the metal can be cleaned from the surface without damaging it
Gallium nitride nanowires grown by PML scientists may only be a few tenths of a micron in diameter, but they promise a very wide range of applications, from new LEDs and diode lasers to ultra-small resonators, chemical sensors, and highly sensitive atomic probe tips.
