Mentor: Imran Mirza, Ph.D. In this poster, we review the integer quantum Hall effect for standard electronic systems. We find that the Hall resistance in 2D materials is quantized into fixed values ...

Purdue University doctoral student Yang Xu, lead author of a new research paper on "topological insulators," an emerging class of materials that could make possible "spintronic" devices and practical ...

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 ...

Electrons have been seen uniting into entities with fractions of electric charge, this time without a magnetic field coaxing them into it. In the 127 years since the electron was discovered, it has ...
