We propose a novel single photon detector for quantum information processing and for general applications in areas where the detection of ultra weak photon fluxes is required. The detector is also capable of discriminating between different numbers o

We investigate charge pumping in semiconducting carbon nanotubes by a travelling potential wave on the surface of a piezoelectric quartz substrate. We estimate the magnitude and profile of the potential wave as its passes the nanotubes and show how t

We have measured the noise at ∼1.6 MHz in the current produced by a surface acoustic wave (SAW) single-electron pump. The current can be varied by altering the voltage applied to surface gates. Over the range of gate voltage where the current is cl

Over the last few years we have developed a new method to control single-electrons by isolating and moving them through a submicron width channel formed in a GaAs/AlGaAs heterostructure using a surface acoustic wave. The acoustic wave acts to push el

A cryogenic amplifier for ∼100 kHz to a few MHz is presented which uses a commercially available pseudomorphic GaAs/InGaAs high electron mobility transistor and dissipates less than 0.5 mW in the cryogenic stage. The input-referred voltage noise an

A surface acoustic wave propagating within a resonant-tunneling structure modulates the rate of electron tunneling and creates a charge density wave in the depletion region of the structure. The charge wave acts piezoelectrically on the surface acous

The effect of a perpendicular magnetic field on the quantized current induced by a surface acoustic wave in a quasi-one-dimensional channel is studied. The channel was defined in a GaAs heterostructure by a shallow-etching technique. The quantized cu

We consider a wide parabolic GaAs/AlGaAs quantum well placed between two metal plates so that direct current can flow across the well. Sloshing plasma oscillations of the charge stored in the well modulate the direct current and charges on the plates
