Film bulk acoustic resonators (FBARs) and solidly mounted resonators (SMRs) have the potential to significantly improve upon the sensitivity and minimum detection limit of traditional gravimetric sensors based on quartz crystal microbalances (QCMs) a

We investigate the sputter growth of very thin aluminum nitride (AlN) films on iridium electrodes for electroacoustic devices operating in the super high frequency range. Superior crystal quality and low stress films with thicknesses as low as 160 nm

Genetic analysis of fingernail debris: application to forensic casework

Autor: M.J Iturralde, J. Capilla, Fernández-Rodriguez A, M. Sancho, L Fernández de Simón

Publikováno v: International Congress Series. 1239:921-924

DNA typing of fingernail debris in cases in which a struggle is suspected can be a relevant issue in forensic casework. In this study, we analyzed 106 samples of fingernail material from 40 forensic cases. A mixture of the victim and the offender was

This study focused on the selective deposition of Au0 onto (111), (100) faces and (111)/(100) edges of cuboctahedral Pt particles present on the Pt/C(graphite) model system. The Pt–Au/C catalysts were prepared by novel surface redox methods involvi

Induced surface roughness to promote the growth of tilted-AlN films for shear mode resonators

Autor: M. DeMiguel-Ramos, Marta Clement, J. Sangrador, Enrique Iborra, J. Olivares, J. Capilla

Publikováno v: 2013 Joint European Frequency and Time Forum & International Frequency Control Symposium (EFTF/IFC).

Two methods currently used to induce surface roughness that promotes the growth of AlN tilted grains to fabricate shear mode resonators have been investigated. The first one involves the use of a rough substrate to provide tilted facets on which the

Acoustic properties of carbon nanotube electrodes in BAW resonators

Autor: Santiago Esconjauregui, William I. Milne, M. DeMiguel-Ramos, Jimena Olivares, Teona Mirea, Luis Garcia-Gancedo, Enrique Iborra, Andrew J. Flewitt, Marta Clement, J. Capilla, Jesús Sangrador

Publikováno v: 2013 Joint European Frequency and Time Forum & International Frequency Control Symposium (EFTF/IFC).

In this paper the acoustic characterization of a layer of carbon nanotubes (CNT) deposited on AlN solidly mounted resonators is described. The structure of the CNT layer is analyzed by scanning electron microscopy and Raman spectroscopy. The electric

Piezoelectric and electroacoustic properties of V-doped and Ta-doped AlN thin films

Autor: Mikhail Mikhov, Enrique Iborra, Valeriy Felmetsger, Marta Clement, J. Capilla, Jimena Olivares

Publikováno v: 2013 Joint European Frequency and Time Forum & International Frequency Control Symposium (EFTF/IFC).

In this paper we analyze the effects of doping AlN films with vanadium and tantalum to concentrations up to 6% atomic. The structure and composition of the new compounds are assessed as a function of the dopant concentration by x-ray diffraction (XRD
