From quantum dots to quantum wires: Electronic structure of semiconductor nanorods
نویسندگان
چکیده
The transition bridge between zero-dimensional quantum dots and one-dimensional quantum wires is explored theoretically by means of the construction of the addition energy spectra of nanorods with different lengths. Spin density-functional theory supplemented with full configuration interaction calculations are carried out. The addition energy spectra are qualitatively related to the single particle correlation diagram. The transition from charge-density waves to spin-density waves, characterizing the Wigner crystallization in the low density limit is shown.

Conductance in quantum wires by three quantum dots arrays
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 fo...
متن کاملOptical Properties of Semiconductor Nanorods
The optical properties of nanocrystals are dictated by their electronic structure, and we start this section with discussing the behavior of electron–hole pairs, the so called excitons, in confined systems. We then describe the optical peculiarities of semiconductor nanorods by highlighting the main characteristics that distinguish them from the more traditional quantum dots. The first part of ...
