A wafer-thin flake of bismuth telluride can act a little like a one-way street for electricity, even when the push comes from ...

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 ...

Scientists have pulled off a feat long considered out of reach: getting light to mimic the famous quantum Hall effect. In ...

This paper introduces Hall-effect technology and then explores how it has been applied, in particular, differentiating between the primary types of Hall sensor ICs, and the highly differentiated range ...

The A139x family, released by Allegro since 2005, is a Hall-effect sensor IC family that has only 10 mW power consumption in the active mode with tri-state output and user-selectable sleep mode. A ...

A research team from Nanjing University has developed an in-situ on-device electrochemical intercalation method to manipulate the structural and electronic properties of MoS 2 thin flakes, resulting ...

A new study examined the mechanism governing the nonlinear Hall effect, paving the way for battery-free devices.

Sensing current, especially in higher-voltage settings, is often a challenge. It’s generally more difficult than voltage sensing, as it is usually “invasive” and requires “breaking” into the ...

A group of scientists has created a quantum material where electricity can flow without losing energy as heat. Until now, this was only seen in ...

The technique is called high-side current sensing. However, measurements at that location are fraught with problems. Of primary concern is that the measurement is at main line voltage, a problem if ...
