Surface| Zusammenfassung: | In terms of the second-order perturbation theory In switching frequencies for opposite-signpotentials, it is demonstrated that the velocity direction of a Brownian motor is determined solely by the difference of these frequencies and the velocity magnitude decreases monotonically from some non-zero value as the temperature increases. For fluctuations pf potential profiles not only in sign but also in magnitude, there can be stopping points where the motion direction changes, which can be applied for nanoparticle segregation |
