How can we explain that beryllium has positive charge carriers as a metal (from Feynman Lectures)?
This question naturally arises from reading Feynman Lectures Vol III 14-3 The Hall effect, online available here, where Feynman states the following:
The original discovery of the anomalous sign of ...

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 ...

Longitudinal conductivity from density of states (DOS)
It is well-known that using the so-called Streda formula, the transversal conductivity $\sigma_{xy}$ and thus the Hall conductivity in a two-dimensional material is given as the derivative of the ...

The mechanism behind the Lorentz force [duplicate]
It has been known for 130 years that a moving electron entering an external magnetic field is deflected (Lorentz force, Hall effects, synchrotrons). What I have never read is a description of how this ...
