Lifshitz-Kosevich formula: ΔR/R ∝ Σ_r R_T(r)·R_D(r)·cos(2πr(F/B − ½) ± π/4), where F = ℏA_F/(2πe) is the SdH frequency related to the Fermi surface extremal cross-section A_F. The thermal damping factor R_T = (2π²rk_BT/ℏω_c)/sinh(2π²rk_BT/ℏω_c) kills oscillations above T ~ ℏω_c/2π²k_B ≈ m*/m × 14K/T. The Dingle factor R_D = exp(−2π²rk_BT_D/ℏω_c) reflects impurity broadening (T_D = ℏ/2πk_Bτ).
