By means of surface acoustic waves we dynamically control: 1) the optoelectronic properties of semiconductor nanostructures such as nanowires or quantum dots, for single photon emitters and 2) integrated photonics structures, for the realisation of tunable devices.
Microelectronic design of polarisation, conditioning and acquisition circuits for the sensors described. For polarisation we study advanced current sources, oscillators, multiplexed excitations... We work with advanced amplifiers with specific characteristics (lock-in, low noise...).
Growth of materials using the techniques of: Bridgman, travelling heater method (THM), physical vapor deposition (PVD), metalorganic chemical vapor deposition (MOCVD), spray pyrolysis (SP). Currently, different types of oxides (CdO, MgO, ZnO and alliatges) are being grown.
Development of solid-state magnetic sensors based on the giant magnetoresistance (GMR) effect. Design of optimal application-oriented structures. Complete definition of the manufacturing process. Comprehensive analysis including finite element modelling (FEM) and electrical and functional characterisation: sensitivity, thermal drifts, noise level, frequency response, etc. Proposal, development and evaluation of applications: electrical current measurement, gradiometers.
Preparation of macroscopic and microscopic nanoporous materials for the development of energy sources, catalyst or nano-container sources. This line of research aims to propose alternative applications of well-established materials in completely different fields, innovating in the application but benefiting from the existing know-how. We focus on post-synthesis surface modifications, filling, and compound (antibiotic) release.
