    Chemistry, Function, and Fate of Acrylamide-Based Polymers

    Acrylamide-based polymers are used widely in water and wastewater treatment to enhance flocculation processes. It is often assumed that a polymer’s molecular weight and its type and amount of electrical charge...

    Electronic Properties of InAs-GaSb and Related AlSb Superlattices

    We describe the InAs-GaSb superlattices and quantum wells with emphasis on their transport and optical properties. We include related structures of InAs-AlSb and GaSb-AlSb which are of interest in their own ri...

    Low-Temperature Magnetotransport in InAs-GaSb Quantum Wells

    We report measurements of the magneto and Hall resistance in GaSb-InAs-GaSb heterostructures at magnetic fields up to 28T and temperatures as low as 0.005K. In addition to the quantized Hall effect, extraordin...

    Fractional Hall Quantization of Two-Dimensional Holes in Gaas-GaAlAs Heterostructures

    The quantum Hall effect in two-dimensional electron systems has been reported in a number of heterostructures,1–4 in which the Hall resistance, ρxy =h/νe2, shows plateaus at integral values of ν and the magneto-r...

    Resonant Electron Transport in Semiconductor Barrier Structures

    We report the transport properties in semiconductor structures consisting of narrow potential wells (GaAs)and barriers (GaA1As). The structures, fabricated by molecular-beamepitaxy, have been evaluated by X-ra...
