Figure 4.

Migration velocity vs DC offset obtained from the refined simulation for 4.4 µm particles at U_ac = 275 V/cm and U_dc < U_ac. μ_dep of −6.4 × 10⁻¹⁹ m⁴·V⁻²·s⁻¹ (solid square) resulted in much slower velocities than the experimental data (solid diamond) at U_dc ≤ 135 V/ cm, while μ_dep of −1 × 10⁻¹⁹ m⁴·V⁻²·s⁻¹ (cross symbol) even showed normal behavior. The best match of the parameter sweep of μ_dep with the experimental data was found at μ_dep between −3 (solid triangle) and −4 × 10⁻¹⁹ m⁴·V⁻²·s⁻¹ (solid circle).
