Quantum mechanics of electrons in strong magnetic field
... To obtain a more concrete idea about the size of the gap between two adjacent Landau levels, we estimate itthe Landau gap. In a typical metal in the field B of the order 10T and taking electron mass me ' 10−27 g, one can estimate the gap roughly as ~Ω = ~eB/me c ' 1.5 ∗ 10−15 erg ' 15K. In a semico ...
