    Does somebody know what are the units of the parameters used in brinkmans equation?

    If, by Brinkman's equation, you mean something like:

    0 = -@P/@z + mu*Del^2(U) - k*U, meaning Poiseuille flow with an extra
    friction term, then the parameter 'k' is a coefficient of friction,
    with units of viscosity/area. 'mu' is the dynamic viscosity.

    thanks for the reply Andy.. But the tunneling equation that i'm concerned about is the tunneling one..

    The equations are:
    G(V)/G(0)=1-(Aodelta phi)/(16 phi bar^(3/2))*eV+(9Ao^2/128 phi bar)(eV)^2
    and
    Ao=4(2m)^1/2 * d/3h

    The equations are the equations 7 and 8 of this paper
    "Tunneling Conductance of Asymmetrical Barrieers", W.F. Brinkman, R.C. Dynes and J.M Rowell
    i want to know the units of these parameters used in this equation
