Light emission from hot carriers in polar semiconductor devices
(SPIE, 1993)We present a theoretical study of hot-carrier induced light emission in III-V semiconductor devices. Carrier heating under the intense electric fields present under high bias conditions are studied via a selfconsistent ... -
Atomistic tight-binding calculations for the investigation of transport in extremely scaled SOI transistors
(IEEE, 2003)This paper reviews the basic methodology and highlights advantages and recent applications of atomistic tight-binding calculations for the investigation of carrier transport in extremely scaled SOI transistors. The ... -
Optical and Electronic Properties of GaN Based Heterostructures: A Self-Consistent Time-Dependent Approach
(Wiley-VCH Verlag, 2001)We present a study of optical properties in GaN based structures and devices. Our approach is based on a rate equation model, where the role of carrier screening on recombination rates is self-consistently included. We ... -
Breakdown dynamics and RF-breakdown in InP-based HEMTs
(IEEE, 2002)In this paper, two approaches to enhance the breakdown voltage in InP-based lattice matched HEMT (InP-LMHEMT) have been investigated by means of a Monte Carlo simulator. In the first we have studied the effects of channel ... -
Carbon nanotube/conducting polymer composites for electronic application: Materials preparation and devices assembling
(IEEE, 2004)In this work we describe the preparation of patterned Carbon Nanotubes / Conducting Polymers composite electrode. The synthetic methodology consists in an in situ electropolymerization of the monomer in the presence of ... -
Density-functional based tight-binding calculations on thiophene polymorphism
(University of Glasgow, 2000)In this work we present the results of density-functional based tight-binding (DFTB) calculations on the inter-molecular interaction of the following thiophene crystals: /spl beta/-tetramethyl-quaterthiophene (TM4T), ... -
Piezoresistive behaviour of single wall carbon nanotubes
(IEEE, 2004)Correlation between mechanical deformation and conductivity behaviour of free-standing membranes of single walled carbon nanotubes (SWCNTs) has been successfully investigated. The aim of this study is proposing this kind ... -
Atomistic simulation of the electronic transport in organic nanostructures: Electron-phonon and electron-electron interactions
(IEEE, 2004)The evaluation of the electron-phonon interactions in molecular systems was carried out with the formalism of non-equilibrium Green's function approach (NEGF). The electron-phonon coupling was derived from the density-functional ...
