Inter-dimensional effects in nano-structures

Inter-dimensional effects in nano-structures

: We report on two extensions of the traditional analysis of low-dimensional structures in terms of low-dimensional quantum mechanics. On one hand, we discuss the impact of thermodynamics in one or two dimensions on the behavior of fermions in low-dimensional systems. On the other hand, we use both quantum wells and interfaces with different effective electron or hole mass to study the question...

Computational study of energy filtering effects in one-dimensional composite nano-structures

Two-dimensional plasmonic nano-structures for linear and nonlinear regimes

In this contribution we provide an overview of our recent research results on the optical properties of 2D array of gold patches immersed in homogeneous and asymmetric environment. The investigated structure acts as a biosensing platform that exploits the formation of a plasmonic band gap in the reflection spectrum.

3D nano-structures for laser nano-manipulation

The resputtering of gold films from nano-holes defined in a sacrificial PMMA mask, which was made by electron beam lithography, was carried out with a dry plasma etching tool in order to form well-like structures with a high aspect ratio (height/width ≈ 3-4) at the rims of the nano-holes. The extraordinary transmission through the patterns of such nano-wells was investigated experimentally and ...

Size Effects on Mechanical Properties of Micro/Nano Structures

Experiments on Microand Nano-mechanical systems (M/NEMS) have shown that their behavior upon bending loads departs in many cases from the classical predictions using Euler-Bernoulli theory and Hooke’s law. This anomalous response has usually been seen as a dependence of the material properties with the size of the structure, in particular thickness. A theoretical model that allows for quantitat...
