Directors: Francesca Peiró i Martínez and Jordi Arbiol i CobosSemiconductor nanowires have recently attracted a lot of interest as potential building blocks for future electronic and optoelectronic nanodevices. In this work structural and optical properties of semiconductor nanowires are studied by means of high resolution transmission electron microscopy (HRTEM) and hotoluminescence (PL) analysis respectively. Several samples of GaAs nanowires grown under different As4 pressures are studied, and the presence of different optoelectronic properties are discussed in relation to the crystalline structures and defects found.9 p.application/pdfengcc-by-nc-nd (c) Conesa Boj, 2008http://creativecommons.org/licenses/by-nc-nd/3.0/es/NanotecnologiaSemiconductorsMicroscòpia electrònica de transmissióFotònicaPropietats òptiquesTreballs de fi de màsterNanotechnologySemiconductorsTransmission electron microscopyPhotonicsOptical propertiesMaster's thesesinfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccess
