Temperature influence on Hall Effect for semiconductor

Currently, I'm taking a course in modern physics experiments and last week I was asked to study the hall effect in a semiconductor. One of the experiments was with a germanium chip where a steady ...

In Hall Effect Thrusters, how is the radial magnetic field generated?

In Hall Effect thrusters, there is a radial magnetic field coming out of the center of the thruster, and runs perpendicularly to an electric field. In most of the diagrams I've seen there is an inner ...

Deriving classical Hall effect from quantum Hall effect

I'm interested in the derivation of the classical Hall effect coefficient, given in cgs by $$R_{H}=-\frac{1}{nec},$$ where $n$ is the electron number density, $-e<0$ is the electron charge,and $c$ ...

Are anomalous Hall effect and spin Hall effect mutually exclusive?

In many papers that cover an analysis of hall effects, the spin hall effect is often qualitatively described as being nearly the same as the anomalous hall effect except for the fact that it doesn't ...

Topological Hall Effect vs. Anomalous Hall Effect

Is the Topological Hall Effect just another name for the Anomalous Hall Effect in a system that isn't ferromagnetic? That is, will some papers refer to this phenomena as "Topological Hall Effect" ...

Is there any instance when a current in Hall effect passes in the vertical direction?

In Hall effect when a magnetic field is applied in transverse direction (z) in sample (conductor/semiconductor) a vertical (y) voltage is developed, because some charges are deflected from the ...

spot welding technique

I am trying to make electrical contacts by the spot welding technique. For Hall effect measurements, the contact size should be as small as possible and the sample is very very thin(0.025mm). But ...

Charge carriers type: contradiction between Hall effect and Seebeck effect, how to resolve it?

On one hand the Hall effect consists of a voltage that arises when an electric field and a perpendicular magnetic field are in a material. This makes the charge carriers (electrons or holes) under the ...
