    Notes: We present the results of a two-dimensional simulation of the amplification of an ambipolar current flow in a four-terminal crystalline silicon device by charge induced into this flow from an insulated gate electrode. We show that although a bipolar current flow in a crystalline device can indeed be modulated by a gate field, the magnitude of this modulation is less than in amorphous silicon double-injection field-effect transistors. Our proposed structure also has an interesting feature in that the gate field redistributes the current flow between its terminals.

    Asymptotic solutions of steady magneto-fluid-dynamic motion between two rotating disks with a small gap (1987)

    Notes: The steady-state flow of a conducting fluid between two coaxial rotating disks in the presence of an axial magnetic field is considered for the following conditions: (1) the gap d between two disks is very small compared with the radial extension of the disks R; (2) the angular velocity of the disks is not too high, so that the thickness of the Eckman layer δ is still larger than the gap d, (d/δ)1/4(very-much-less-than)1; and (3) the magnetic field B is moderate so that the corresponding Hartman number M(very-much-less-than)R2/d2. Under these conditions asymptotic solutions to the problem are obtained in terms of the small parameter Ε=d/R. The results show that to the lowest-order approximation, the electric properties of the disks are not important to the flow field, while the magnitude of the magnetic field plays an important role in the equilibrium flow profile.
