Chaos research applied to nano-chemistry

28-Feb-2023

Sometimes, chemical reactions do not solely run stationary in one direction, but they show spatio-temporal oscillations. At TU Wien, a transition to chaotic behavior on the nanometer scale has now been observed. Chaotic behavior is typically known from large systems: for example, from weather, ...

The smallest semiconductor composed of only 27 atoms, the Cd14Se13 cluster, has an interesting core-cage structure

05-Aug-2022

A semiconductor is a material whose conductivity lies somewhere between that of a conductor and an insulator. This property allows semiconductors to serve as the base material for modern electronics and transistors. It is no understatement that the technological progress in the latter part of the ...
