Journal ArticleDOI
The complete Raman spectrum of nanometric SnO2 particles
TL;DR: In this article, the authors present a complete Raman spectrum analysis of SnO2 nanoparticles, which comprises modification of the normal vibration modes active in Raman when the spectra are obtained from nanocrystals of Sn O 2 nanoparticles in the region around 475 −775 cm 21, and the appearance of the acoustic modes in the low-frequency region of the spectrum.
Journal ArticleDOI
High mobility indium free amorphous oxide thin film transistors
Elvira Fortunato,Luís Pereira,Pedro Barquinha,Ana M. Botelho do Rego,Gonçalo Gonçalves,Anna Vilà,Juan Ramon Morante,Rodrigo Martins +7 more
TL;DR: In this article, the effect of postannealing temperatures (200, 250, and 300°C) was evaluated and compared with two series of TFTs produced at room temperature (S1) and 150°C (S2) during the channel deposition.
Journal ArticleDOI
Gallium–Indium–Zinc-Oxide-Based Thin-Film Transistors: Influence of the Source/Drain Material
Pedro Barquinha,Anna Vilà,Gonçalo Gonçalves,Luís Pereira,Rodrigo Martins,Joan Ramon Morante,Elvira Fortunato +6 more
TL;DR: In this article, the authors investigated different materials to replace ITO in inverted-staggered TFTs based on gallium-indium-zinc oxide (GIZO) semiconductor.
Journal ArticleDOI
Role of Ga2O3–In2O3–ZnO channel composition on the electrical performance of thin-film transistors
Antonis Olziersky,Pedro Barquinha,Anna Vilà,C. Magaña,Elvira Fortunato,Joan Ramon Morante,Rodrigo Martins +6 more
TL;DR: In this paper, the role of channel layer composition on the electrical performance and stability exhibited by thin-film transistors was investigated by magnetron sputtering using ceramic targets of different compositions.
Journal ArticleDOI
Micromachined twin gas sensor for CO and O2 quantification based on catalytically modified nano-SnO2
J. Cerdà Belmonte,J. L. Manzano,Jordi Arbiol,Albert Cirera,J. Puigcorbé,Anna Vilà,Neus Sabaté,Isabel Gràcia,Carles Cané,Joan Ramon Morante +9 more
TL;DR: In this article, a micromachined twin sensor that can distinguish between carbon monoxide (CO) and O2 gas taking advantage of the high sensitivity of SnO2 to these gases is presented.
