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 carrier-resolved photo-Hall effect. Courtesy: O Gunawan/IBM A new technique to extract information on the mobility of electrons and holes in semiconductors has unlocked a long-held secret in the ...
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 ...
Hall effect plays an important role in the development of condensed matter physics. The classical Hall effect was discovered by American physicist E. H. Hall in 1879. When an electric current passes ...
I am sitting alone at the head of a large conference table when an oddly familiar voice greets me: “Hey, you must be Spiros!” I turn around to find Paul Rudd, the Hollywood actor, wearing his famed ...
On an autumn day in 1879, Edwin Hall was at his bench in Johns Hopkins University's physics lab, a converted kitchen off Baltimore's North Howard Street called the Annex. The third-year graduate ...
