ABSTRACT
We report the characterization of a single-electron transistor based on bended wires fabricated on modulation-doped SiGe two-dimensional electron gas. Electrical measurements show a diamond-shaped stability plot and a nonperiodic sequence of conductance peaks. The device behavior suggests the presence of disorder-induced multiple islands along the wire. Conductance oscillations remain well pronounced above liquid helium temperature.

    Recently, Yamamoto et al. have carried out torsional oscillator measurements for 4He filled in a nanoporous glass containing pores 2.5 nm in diameter (Gelsil), and reported a large suppression of superfluidity at high pressures. In order to study the mechanism of the superfluid suppression, we...

    Liquid helium becomes a superfluid and flows with zero viscosity at low temperatures. Superfluidity is manifested by a failure to rotate, as its mass is decoupled from the rotation of the containing cell. Supersolid helium should show similar behaviour; apparent rotational inertia decreases when...
