Creating and trapping trions at room temperature

16 октября, 2019 - 17:42
A team chemically engineered carbon nanotubes to synthesize and trap trions at room temperature. Trions are quasi particles that can potentially carry more information than electrons in applications from bioimaging to chemical sensing and quantum computing. The research makes it possible to manipulate trions and study their fundamental properties in ways that have never been possible before.

Metal to metal oxide progression

16 октября, 2019 - 17:42
A catalyst's utility is influenced by its surface charge and how that charge is transferred. Until recently, studying charge transfer has relied on complex imaging techniques that are both expensive and time-consuming. Scientists now report an approach for studying charge transfer that does not rely on complicated equipment -- simplifying the real-time observation of catalysis.

Controlling the charge state of organic molecule quantum dots in a 2D nanoarray

15 октября, 2019 - 17:33
Researchers have fabricated a self-assembled, carbon-based nanofilm where the charge state (ie, electronically neutral or positive) can be controlled at the level of individual molecules. Molecular self-assembly on a metal results in a high-density, 2D, organic quantum-dot array with electric-field-controllable charge state, with the organic molecules used as 'nano-sized building blocks' in fabrication of functional nanomaterials. Achieved densities are an order of magnitude larger than conventional inorganic systems.

The nano-guitar string that plays itself

14 октября, 2019 - 18:17
Scientists have created a nano-electronic circuit which vibrates without any external force. Just as a guitar string vibrates when plucked, the wire -- 100,000 times thinner than a guitar string -- vibrates when forced into motion by an oscillating voltage. The surprise came when they repeated the experiment without the forcing voltage. Under the right conditions, the wire oscillated of its own accord. The nano-guitar string was playing itself.
