Researchers are proposing a new way to modulate both the absorptive and the refractive qualities of metamaterials in real time, and their findings open intriguing new opportunities to control, in time and space, the propagation and scattering of waves for applications in various areas of wave physics and engineering.
Applying a thin invisible layer of graphene oxide to silicon forms an impermeable barrier, which could be used to protect artwork, prevent corrosion of metals, and produce higher efficiency solar cells.
A new method for manufacturing electronics which prints high-performance silicon directly onto flexible materials could lead to breakthroughs in technologies including prosthetics, high-end electronics and fully bendable digital displays.
Negative differential resistance (NDR), which describes a decrease in electrical current as the applied bias increases, has always been one of the hottest topics in solid-state electronic devices since L. Esaki first demonstrated this phenomenon in heavily-doped Ge p?n junctions in 1958. Researchers now report the modulation of a unique room-temperature NDR effect with high peak current in ambipolar black phosphorus transistors. The simplicity of this structure, combined with the recent ...
Electrons flow like a viscous fluid through a 2D channel with perfectly smooth sidewalls, offering a new platform to test solid-state and fluid dynamics theories
