Questions and Answers

How does the Fermi level depend on the magnetic quantum number s?

The Fermi level will lie in the Landau level s 1 if there are electrons in this level.

What happens to the Fermi level when the Landau level s 1 is vacated?

It moves down abruptly to the next lower level s.

What happens to the electron transfer to lower Landau levels as the magnetic field is increased?

It can occur because their degeneracy D increases as B is increased.

What happens to the orbitals at the next higher level s 1 when the Landau level s is partly filled?

<p>They will be partly filled to the extent needed to accommodate the electrons.</p> Signup and view all the answers

How are the Landau levels filled for a system of N electrons at absolute zero?

<p>The Landau levels are entirely filled up to a magnetic quantum number identified by s, where s is a positive integer.</p> Signup and view all the answers
