Nanotechnology is ushering in the era of self-replicating machinery and self-assembling consumer goods made from raw atoms. Utilizing the well understood properties of atoms & molecules, nanotechnology proposes the construction of novel molecular devices possessing extraordinary properties. The single electron transistor or SET is a new type of switching device that uses controlled electron tun...

We present an experimental demonstration of a latch in a clocked quantum-dot cellular automata ~QCA! device. The device consists of three floating micron-size metal dots, connected in series by multiple tunnel junctions and controlled by capacitively coupled gates. The middle dot acts as an adjustable barrier to control single-electron tunneling between end dots. The position of a switching ele...

In this work, we investigate the dynamics of a single electron surface trap, embedded in a self-assembly metallic double-dot system. The charging and discharging of the trap by a single electron is manifested as a random telegraph signal of the current through the double-dot device. We find that we can control the duration time that an electron resides in the trap through the current that flows...

We investigate theoretically the transport characteristics of a single-electron transistor affected by the dynamic deformation of the device configuration due to phonons. By considering changes in capacitances and tunnel resistances caused by the breathing and oblong vibrations of the island that forms part of the transistor, we formulate the electron-phonon interaction peculiar to the device a...

In this paper, we review the current status of nanoelectronic devices based on quantum effects such as quantization of motion and interference, and those based on single electron charging phenomena in ultrasmall structures. In the first part, we discuss wave-behavior in quantum semiconductor structures, and several device structures based on quantum waveguide behavior such as stub tuners, Y-bra...

We demonstrate dispersive readout of individual charge states in a gate-defined few-electron quantum dot bilayer graphene. employ radio frequency reflectometry circuit, where an LC resonator with resonance close to 280 MHz is directly coupled Ohmic contact the device. The detection scheme based on changes capacitance operates over wide gate-voltage range and allows us probe excited down single-...

Among the exotic and yet unobserved features of multi-channel Kondo impurity models is their sub-unitary single electron scattering. In two-channel model, for example, an incoming fully scattered into a many-body excitation such that particle Green function vanishes. Here we propose to directly observe these in charge-Kondo device encapsulated Mach-Zehnder interferometer - within already studie...
