Researchers at the Faculty of Materials Science and Engineering at the Technion succeeded in changing the electrical properties of a material by removing an oxygen atom from the original structure. Possible applications: electronic miniaturization and detection of radiation emissions
A series of grooves on a metal surface can guide plasmonic waves. The waves are produced on the left by the laser striking the grating, and the waves are measured on the right by a near-field scanning optical microscope. Credit: D. Wiseman and others.

Organic topological insulators capable of transmitting information at the speed of light and which consist of a thin molecular layer (on the left) that resembles a sort of chicken coop fence wire while conducting electricity along the right edge of this layer (the blue line) - when the electrons can also carry information in the form of "down" or "up" spin ".

Engineers demonstrate the capability of superfast materials

Researchers discovered that in the material TbFeO3 there is a magnetic field in which the change in the spin direction along a certain line of the atoms occurs suddenly. In the lower picture, a magnetic complex is depicted, the strength of which is obtained due to the large amount of complexes with the same direction. The top image depicts complexes that appear in more ordinary materials, where the spin rotates at a slower rate from up to down.

A very narrow bridge: is it possible to produce electronic components whose size does not exceed that of a single molecule?

Scanning electron microscope image of a gold bridge suspended 40 nm above a silicon substrate. In the experiment, the bridge is cut in the middle, a single electrode is suspended in the resulting gap, and the substrate is bent to stretch the electrode while measuring the electron current passing through it.

In "heavy fermion" materials, free electrons used for electrical conduction react strongly with atoms and sink to low energy levels before re-emerging and continuing on their way. Their slow progress makes them look heavy. Photo by Mohammad Hamidian/Davis Lab
