In this work we study the effects of topology on the coherent single-electron transport through junctions of nanotuhes with different chiralities. The junctions are modeled as cylindrical surfaces with variable radius. The quantum dynamics of the particle hound to a curved surface is described by a modified Schroedinger equation depending on two curvilinear coordinates. The transmission coefficients are computed hy numerically solving the equation for a number of different geometries. Our results show how the topology of the nanotuhe structure is reflected onto the coherent transport characteristics of the system.

Abstract
In this work we study the effects of topology on the coherent single-electron transport through junctions of nanotuhes with different chiralities. The junctions are modeled as cylindrical surfaces with variable radius. The quantum dynamics of the particle hound to a curved surface is described by a modified Schroedinger equation depending on two curvilinear coordinates. The transmission coefficients are computed hy numerically solving the equation for a number of different geometries. Our results show how the topology of the nanotuhe structure is reflected onto the coherent transport characteristics of the system.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
