The increase of the annealing temperature revealed that significant morphological modifications were induced, mainly in the samples with higher Ag contents (represented by the sample with an Ag content of 36.3 at. %), which revealed extensive Ag segregation to the surface. The increase of the annealing temperature up to 500\u2009\u00b0C, besides confirming the presence of metallic Ag in the coatings, also resulted in some major structural changes, promoting an increase in the coating's crystallinity and an extensive Ag grain growth phenomenon. Nevertheless, the resistivity values of all annealed samples were found to be only slightly higher when comparing to the as-deposited ones, which indicated that beyond the significant changes in the samples morphology (e.g., Ag segregation), there seemed to be some important coating resistance in terms of the electrical response. Furthermore, the annealed samples also exhibited lower reduced modulus up to 400\u2009\u00b0C when compared with the unannealed ones, consistent with some increase of the samples' elasticity.<\/jats:p>","DOI":"10.1116\/1.4873555","type":"journal-article","created":{"date-parts":[[2014,5,2]],"date-time":"2014-05-02T00:31:04Z","timestamp":1398990664000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":6,"title":["Ag:TiN nanocomposite thin films for bioelectrodes: The effect of annealing treatments on the electrical and mechanical behavior"],"prefix":"10.1116","volume":"32","author":[{"given":"Paulo","family":"Pedrosa","sequence":"first","affiliation":[{"name":"University of Coimbra SEG-CEMUC\u2014Department of Mechanical Engineering, , 3030-788 Coimbra, Portugal; Universidade do Porto, Faculdade de Engenharia, Departamento de Engenharia Metal\u00fargica e de Materiais, Rua Dr. Roberto Frias, s\/n, 4200-465 Porto, Portugal ; and Centro de F\u00edsica, , 4710-057 Braga, Portugal"},{"name":"Universidade do Minho SEG-CEMUC\u2014Department of Mechanical Engineering, , 3030-788 Coimbra, Portugal; Universidade do Porto, Faculdade de Engenharia, Departamento de Engenharia Metal\u00fargica e de Materiais, Rua Dr. Roberto Frias, s\/n, 4200-465 Porto, Portugal ; and Centro de F\u00edsica, , 4710-057 Braga, Portugal"}]},{"given":"Diogo","family":"Machado","sequence":"additional","affiliation":[{"name":"Centro de F\u00edsica, Universidade do Minho , 4710-057 Braga, Portugal"}]},{"given":"Manuel","family":"Evaristo","sequence":"additional","affiliation":[{"name":"University of Coimbra SEG-CEMUC\u2014Department of Mechanical Engineering, , 3030-788 Coimbra, Portugal"}]},{"given":"Albano","family":"Cavaleiro","sequence":"additional","affiliation":[{"name":"University of Coimbra SEG-CEMUC\u2014Department of Mechanical Engineering, , 3030-788 Coimbra, Portugal"}]},{"given":"Carlos","family":"Fonseca","sequence":"additional","affiliation":[{"name":"University of Coimbra SEG-CEMUC\u2014Department of Mechanical Engineering, , 3030-788 Coimbra, Portugal and Universidade do Porto, Faculdade de Engenharia, Departamento de Engenharia Metal\u00fargica e de Materiais, Rua Dr. Roberto Frias, s\/n, 4200-465 Porto, Portugal"}]},{"given":"Filipe","family":"Vaz","sequence":"additional","affiliation":[{"name":"Centro de F\u00edsica, Universidade do Minho , 4710-057 Braga, Portugal"}]}],"member":"20","published-online":{"date-parts":[[2014,5,1]]},"reference":[{"key":"2023062823203972500_c1","doi-asserted-by":"publisher","first-page":"463","DOI":"10.1016\/S0042-207X(02)00232-4","volume":"67","year":"2002","journal-title":"Vacuum"},{"key":"2023062823203972500_c2","doi-asserted-by":"publisher","first-page":"308","DOI":"10.1016\/j.micron.2008.11.004","volume":"40","year":"2009","journal-title":"Micron"},{"key":"2023062823203972500_c3","doi-asserted-by":"publisher","first-page":"59","DOI":"10.1016\/j.electacta.2009.08.004","volume":"55","year":"2009","journal-title":"Electrochim.
