Recently, [Solder Hub] put together a brief video that demonstrates the basics of a Hall Effect sensor — in this case, one salvaged from an old CPU fan. Two LEDs, a 100 ohm resistor, and a 3.7 volt ...

Researchers in China have observed a novel version of the Hall effect in a single layer of tungsten selenide (WSe 2). The result, which they obtained by applying strain to a sample of the ...

The Hall effect is a mainstream direction in the study of condensed matter physics. Recently, the second-order Hall effect that does not require a magnetic field has recently been discovered in ...

The Quantum Hall Effect was first observed in 1980 by Klaus von Klitzing, for which he was awarded the Nobel Prize in Physics in 1985. It occurs in two-dimensional electron gases found in ...

Beijing Zhongke Journal Publising Co. Ltd. Magnetic chiral DWs are a class of topological structures with discrete symmetries. As the boundary between domains with opposite magnetization, this ...

A research team has successfully developed a technique to reach near-unity efficiency of SHEL by using an artificially-designed metasurface. A POSTECH-KAIST joint research team has successfully ...
