In two dimensions, when classical electrons are subjected to a magnetic field they follow circular cyclotron orbits. When the system is treated quantum mechanically, these orbits are quantized. To determine the values of the energy levels the Schrödinger equation must be solved. Since the system is subjected to a magnetic field, it has to be introduced as a… WebDavid Tong: Lectures on the Quantum Hall Effect. This is a course on the quantum Hall effect, given in TIFR, Mumbai. The first four chapters require only basic quantum mechanics; the final two chapters need techniques from quantum field theory. The full lecture notes are around 230 pages.

WebThis effect is known as Hall effect. What is the resistivity formula? Resistivity, commonly symbolized by the Greek letter rho, , is quantitatively equal to the resistance R of a specimen such as a wire, multiplied by its cross-sectional area A, and divided by its length l; = RA/l. The unit of resistance is the ohm. WebThe inset shows the magnetic field dependence of the low-T Hall resistivity ρ yx (B), exhibiting non-linear behavior fitted by a two-band model (red line), based on the assumption that 2D and 3D electronic states contribute in parallel to transport.
