Quantum Confinement Effect
Condensed Matter & Materials Physics
eV (Confinement Energy Shift)
The shift and quantization of electronic energy levels when charge carriers are confined within spatial dimensions smaller than their De Broglie wavelength.
E_confinement ∝ 1 / L² (When dimension L ≤ De Broglie wavelength)
Quantum Hall Effect
Condensed Matter & Materials Physics
Ω (Von Klitzing Constant R_K ≈ 25812.807 Ω)
A quantum mechanical version of the Hall effect observed in 2D electron gases at low temperatures and intense magnetic fields, where Hall resistance is quantized in integer multiples of h/e².
R_H = h / (ν e²), ν = 1, 2, 3...
