Researchers have used layered materials to create an all-electrical quantum light emitting diodes (LED) with single-photon emission. These LEDs have potential as on-chip photon sources in quantum information applications.
The phenomenon, called flexoelectricity, arises from the redistribution of atoms and electrons in a material when it is bent. This redistribution of charges can be used to generate an electrical current. It was already known that insulating materials can be flexoelectric.
Scientists describe the path to developing a new class of artificial muscles made from highly twisted fibers of various materials, ranging from exotic carbon nanotubes to ordinary nylon thread and polymer fishing line.
Tiny sensors made through nanoscale 3D printing may be the basis for the next generation of atomic force microscopes. These nanosensors can enhance the microscopes' sensitivity and detection speed by miniaturizing their detection component up to 100 times.
Researchers have created an exotic 3-D racetrack for electrons in ultrathin slices of a nanomaterial they fabricated. The international team of scientists observed, for the first time, a unique behavior in which electrons rotate around one surface, then through the bulk of the material to its opposite surface and back.
Scientists have successfully developed room temperature multiferroic materials by a layer-by-layer assembly of nanosheet building blocks. Multiferroic materials are expected to play a vital role in the development of next-generation multifunctional electronic devices.
