Characterization CHANGE TOPIC

Characterization news, October 2020

Researchers have grown twisting spirals by depositing sheets of 2D material on a substrate that was curved slightly by slipping a nanoparticle underneath.

Distorting impurities help improve thermoelectric materials

Researchers have discovered that antimony impurities enhance the efficiency of thermoelectric materials by introducing crystal distortions.

By positioning a metallic probe over a defect in a 2D semiconductor, researchers were able to electrically trigger emission of a single photon.

A new method for testing fatigue in metals at a microscopic scale can predict when early, localized damage will evolve into cracks.

Twisted stacks of bilayer graphene can exhibit highly correlated electron properties, which likely relates to the emergence of exotic magnetic states.

Researchers have discovered a variety of exotic electronic states, including a rare form of magnetism, in a twisted three-layer graphene structure.

Applying strain to tiny needles of diamond can transform their electronic properties from insulating, through semiconducting, to highly conductive.

Using experiments and simulations, researchers have identified the configurations of dislocations that give rise to desirable properties in a model alloy.

3D printing of composite parts makes counterfeiting easier

The movement of oxygen in a perovskite material covered in iron nanoparticles can switch it between highly catalytic and less catalytic states.
