“Science” reveals: Quasicrystals enhance transmission properties.
A research team under Prof. Moti Segev at the Technion Faculty of Physics have shown that quasicrystals unveiled in 1982 by Technion Nobel Laureate Dan Shechtman have advanced properties in transmitting electrons. The research, published in Science, is in direct contradiction to the belief that non-periodic crystals could limit transmission properties of materials. Furthermore, the team revealed that the more the disorder, the more enhanced the expansion of the beam propagating through the medium.

The researchers used an optical system to build a quasi-crystal photon, to track the speed of light.
“The assumption that nature is basically formed of solid, cyclical structures is incorrect,” say the researchers. Until the eighties, all the crystals investigated were composed of a basic structure (unit cell). “However, in 1982 Professor Dan Shechtman revealed evidence of Quasi-cyclical materials in which the atoms / molecules are arranged in Periodic (crystalline) patterns on the one hand, but are scattered randomly on the other. This discovery is shaking the scientific world.” Conclusions from this study have implications for the study of electron conduction.
