چکیده

a noninteracting quantum-dot arrays side coupled to a quantum wire is studied. transport through the quantum wire is investigated by using a noninteracting anderson tunneling hamiltonian. the conductance at zero temperature develops an oscillating band with resonances and antiresonances due to constructive and destructive interference in the ballistic channel, respectively. moreover, we have found the number of antiresonant exactly depends on the number of quantum dot in every array and increasing array make antiresonants wide increase.

Conductance anomalies in quantum wires

We study the conductance threshold of clean nearly straight quantum wires in which an electron is bound. We show that such a system exhibits spin-dependent conductance structures on the rising edge to the first conductance plateau, one near 0.25(2e 2 /h), related to a singlet resonance, and one near 0.75(2e 2 /h), related to a triplet resonance. As a quantitative example we solve exactly the sc...

Nonuniversal Conductance Quantization in Quantum Wires.

We have measured the transport properties of high-quality quantum wires fabricated in GaAs-AlGaAs by using cleaved edge overgrowth. The low temperature conductance is quantized as the electron density in the wire is varied. While the values of the conductance plateaus are reproducible, they deviate from multiples of the universal value of 2e2yh by as much as 25%. As the temperature or dc bias i...

Conductance increase by electron-phonon interaction in quantum wires.

We investigate the influence of electron-phonon interactions on the DCconductance Γ of a quantum wire in the limit of one occupied subband. At zero temperature, a Tomonaga-Luttinger-like renormalization of Γ to a value slightly larger than 2e2/h is calculated for a realistic quantum wire model.

Applications of Quantum Dots in Cell Tracking

Tracking cells after transplantation is always one the main concerns of researchers in the field of regenerative medicine. Finding a tracer with long stability and low cytotoxicity can be considered as a solution for this issue. Semiconductor nanocrystals, also called quantum dots (QDs), have unique photophysical properties which make them as suitable candidate in this setting. Broad-range exci...
