Room-temperature non-reciprocal Hall effect could heat up future technology development

The researchers deposited textured platinum nanoparticles, represented by red triangles, onto a silicon semiconductor, represented by blue squares. Electrons, represented by white circles and arrows, scatter asymmetrically from the nanoparticles, causing a voltage, represented by yellow arrows, flowing perpendicular to the current, represented by black arrows, applied to the semiconductor. The relationship between voltage and current can be described mathematically…
