Computer simulations showed that changing the coverage of the monolayer changed the smoothness of the surface. Both low coverage and high coverage produced very slippery surfaces, but for different reasons. [Source: Sakari Lepikko et al 2023]

The smoothest surface ever created

  • No comments
The smoothness of a surface can be adjusted by changing its roughness at the molecular level - this is how researchers from Finland demonstrate

Researchers synthesized a stable C16 carbon ring, although theoretically it should have broken down immediately

  • One response
Before the successful synthesis, it was not clear if it was even possible to create such a molecule and keep it stable long enough to study its structure and its electronic properties.
- Spin laser on an atomic scale: the image describes the laser resonator structure consisting of two types of nanoantenna structures. The radiation is trapped in the internal structure only (yellow). The active layer of the laser - a single atomic layer - is on the resonator. The laser beam is split into two beams by the opposite spins of the photons (light particles), which can be controlled with the help of the laser pump (credit: Scholardesigner co, LTD).

For the first time: a spin-optical laser at the atomic level - a new horizon for optoelectronic devices

  • No comments
Researchers from the Technion have challenged the limits of what is possible in the field of spin-optics at the atomic level. They developed a spin laser from a single atomic layer - a device that does not require magnetic fields or low temperatures
The atomic structure of the material strontium vanadate (strontium vanadate) - illustration of the atomic structure of the material under tension (right) and compression (left). In the center you can see the true atomic arrangement in the material in an electron microscope image. At the bottom of the picture you can see how the various efforts change the structure of the energy levels in the material and therefore also the way the electrons arrange themselves in it. By controlling these properties, the researchers intend to engineer these materials into future transistors. Photo: Nitzan Zohar, Technion Spokesperson

Researchers at the Technion have developed tiny laser devices for small atomic clocks for the industry

  • No comments
These watches have unique features including small volume and weight and low energy consumption - essential features because they are mobile components powered by batteries. The tiny clock has uses similar to those of normal atomic clocks used for example in navigation systems (GPS), synchronization between communication systems and computer systems.

"Sliding and climbing between electrical polarizations": The periodic crystal structure contains a pair of atoms at regular intervals in each horizontal layer. Each additional layer can be slid to the right or left in the horizontal plane to place a blue atom exactly above a red atom or vice versa, thereby bouncing electrons with an electrical charge up or down between the layers. Unlike in polarized crystals known so far, the electric potential in the new system changes in a constant and well-defined value between each step. It is possible to climb in a controlled manner between all the different options, that is, it is possible to switch between the information units in the same crystal in contrast to a pair of modes in previous technologies.
