Porous materials display enhanced scattering mechanisms that greatly infuence their transport properties. Metal-assisted chemical etching (MACE) enables fabrication of porous silicon nanowires starting from a doped Si wafer by using a metal template that catalyzes the etching process. [...]

17 p, 2.0 MB Thermal boundary resistance in semiconductors by non-equilibrium thermodynamics / Dettori, Riccardo (University of Cagliari.

Departament d'Enginyeria Electrònica) ; Rurali, Riccardo (Institut de Ciència de Materials de Barcelona) ; Colombo, Luciano (Institut Català de Nanociència i Nanotecnologia)
We critically address the problem of predicting the thermal boundary resistance at the interface between two semiconductors by atomistic simulations. After reviewing the available models, lattice dynamics calculations and molecular dynamics simulation protocols, we reformulate this problem in the language of non-equilibrium thermodynamics, providing an elegant, robust and valuable theoretical framework for the direct calculation of the thermal boundary resistance through molecular dynamics simulations.

Metal silicides formed by means of thermal annealing processes are employed as contact materials in microelectronics. Control of the structure of silicide/silicon interfaces becomes a critical issue when the characteristic size of the device is reduced below a few tens of nanometers. [...]

7 p, 4.4 MB NH₃ molecular doping of silicon nanowires grown along the [112], [110], [001], and [111] orientations / Miranda, Álvaro (Universitat Autònoma de Barcelona.

Institut de Ciència de Materials de Barcelona) ; Rurali, Riccardo (Universitat Autònoma de Barcelona. Institut de Ciència de Materials de Barcelona)
The possibility that an adsorbed molecule could provide shallow electronic states that could be thermally excited has received less attention than substitutional impurities and could potentially have a high impact in the doping of silicon nanowires (SiNWs). [...]

18 p, 3.0 MB Thermal transport in porous Si nanowires from approach-to-equilibrium molecular dynamics calculations / Cartoixà Soler, Xavier (Universitat Autònoma de Barcelona.

Dipartimento di Fisica) ; Colombo, Luciana (Università degli Studi di Cagliari. Dipartimento di Fisica) ; Rurali, Riccardo (Institut de Ciència de Materials de Barcelona)
We study thermal transport in porous Si nanowires (SiNWs) by means of approach-to-equilibrium molecular dynamics simulations. We show that the presence of pores greatly reduces the thermal conductivity, κ, of the SiNWs as long mean free path phonons are suppressed. [...]

4 p, 327.5 KB Theoretical evidence for the kick-out mechanism for B diffusion in SiC / Rurali, Riccardo (Centro Nacional de Microelectrónica) ; Godignon, Philippe (Centro Nacional de Microelectrónica) ; Rebollo Palacios, José Andrés (Centro Nacional de Microelectrónica) ; Ordejón Rontomé, Pablo (Institut de Ciència de Materials de Barcelona) ; Hernández, E. (Institut de Ciència de Materials de Barcelona) ; American Physical Society
In this letter, we analyze by means of first-principles electronic structure calculations the diffusion of B impurities in 3C-SiC. We find, through molecular dynamics, that substitutional B at a Si lattice site is readily displaced by a nearby Si interstitial by the process known as a kick-out mechanism, in agreement with recent experimental results.

(Institut de Ciència de Materials de Barcelona) ; Ordejón Rontomé, Pablo (Institut de Ciència de Materials de Barcelona) ; American Physical Society
We report the results of an ab initio study of N and P dopants in SiC. We find that while N substitutes most favorably at a C lattice site, P does so preferably at a Si site, except in n-doping and Si-rich 3C-SiC. [...]

We propose an approach to the fabrication of one-dimensional nanostructures, based on the design of a pattern of channels onto a semiconductor surface. The feasibility of this approach is demonstrated by means of ab initio and empirical electronic structure calculations. [...]

Departament d'Enginyeria Electrònica) ; American Institute of Physics
A micro-electro-mechanical system based vibration energy harvester is studied exploring the benefits of bistable non linear dynamics in terms of energy conversion. An electrostatic based approach to achieve bistability, which consists in the repulsive interaction between two electrets locally charged in both tip free ends of an atomic force microscope cantilever and a counter electrode, is experimentally demonstrated.
