  Free Flow of Electrons!   Electrons are the building blocks of electronic devices and the movement of these electrons plays a crucial role in the functionality of electronic devices. Basically, any electronic conduction requires the movement of electrons and thus it is a very fundamental and important aspect. In traditional metals, electrons are expected to move diffusively, meaning that they behave like individual particles. However, a recent study has discovered a novel behaviour of electrons in a metal called ditetrelide (NbGe2), where electrons behave like a fluid, flowing in a way similar to water in a pipe. This fluid-like behaviour is due to the interaction between electrons and quasiparticles called phonons, which arise from vibrations in the crystal structure of the metal.     This discovery has important implications for the development of new electronic devices as it completely revolutionaries electrical conduction. Let's first look at the tr...

  FLICK, PULSE AND SUPERCONDUCT   WHAT IS SUPERCONDUCTIVITY?   By definition, superconductivity is a state of matter that has no electrical resistance and does not allow magnetic fields to penetrate. For regular conductors, as we know, resistance decreases linearly with temperature and becomes 0 at absolute temperature (0 Kelvin). However, in the case of superconductors, they have a critical temperature — based on their physical properties — below which their resistance drops to 0 ohms. Now, superconductors are of great influence due to their properties and hence find multitudes of applications. However, this also makes them expensive and difficult to obtain.   Graphene, an allotrope of carbon (which is more accessible than currently available superconductors) also acts as a superconductor. However, there is a twist Source: www.maxpixel.net   Graphene is a one-atom-thick layer of carbon atoms arranged in a hexagonal lattice. When multiple gra...
