A wafer-thin flake of bismuth telluride can act a little like a one-way street for electricity, even when the push comes from ...
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 ...
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 ...
In many quantum materials—materials with unusual electrical and magnetic properties driven by quantum mechanical effects—electrons can organize themselves into Landau levels. Landau levels are ...
What is the Hall Effect? The Hall effect is a fundamental phenomenon in physics that occurs when an electric current flows through a conductor in the presence of a magnetic field perpendicular to the ...
