Ferroelectricity – a spontaneous electric polarization
Ferroelectricity is a characteristic of certain materials that have a spontaneous electric polarization that can be reversed by the application of an external electric field.…
Quantum tunneling – a quantum mechanical phenomenon
Tunneling is a quantum mechanical effect. A tunneling current occurs when electrons move through a barrier that they classically shouldn’t be able to move through.…
Magnetoresistance – the tendency of a material to change the value of its electrical resistance
Magnetoresistance, the change of a material’s resistivity with the application of a magnetic field, is a well-known phenomenon. Magnetoresistance is the tendency of a material…
Precision X-Rays Reveal Contents Of Sealed And Folded 17th Century Letters
Long before digital encryption, a wide range of methods used to hide the content of letters from Prize’s eyes. Centuries after the deaths of both…
Tunnel Magnetoresistance
Magnetoresistance is the tendency of a material (often ferromagnetic) to change the value of its electrical resistance in an externally-applied magnetic field. Tunneling magnetoresistance (TMR)…
Memristor – a non-linear two-terminal electrical component
The term Memristor is a passive device that provides functional relation between charge and flux. It is a non-linear two-terminal electrical component relating to electric…
Scientist Have Found The Maximum Speed Of Sound
Thanks to Einstein’s special theory of relativity, we know that the speed of light in space is the limit of the ultimate speed of the…
Watch The First Ever Video Of A Space-Time Crystal
German-Polish collaboration has been able to manage the first video recording of the space-time crystal. The structure of the repeating elements was micrometer in size…
Repeating Gravitational Waves Could Reveal The Shape Of Merged Black Holes
Black holes are rather featureless, defined simply by their spin and mass. When two black holes merge, the result is a brief appearance of something…
Precariously Balanced Rocks Improve Precision Of Earthquake Forecasts
The rocks look like they will go down if you give them a little stimulus and more than great backdrops for taking selfies. They can…
Spin-transfer torque
Spin-transfer torque (STT) is an effect in which the orientation of a magnetic layer in a magnetic tunnel junction or spin valve can be modified…
