Journal ArticleDOI
A new approach to the growth of ZnO by vapour transport
Vicente Muñoz-Sanjosé,Ramón Tena-Zaera,C. Martínez-Tomás,Jesús Zúñiga-Pérez,Said Hassani,Robert Triboulet +5 more
TL;DR: In this article, a new interpretation of the chemical role of some of these species was proposed, which considers that, in some cases, the additional species promote a partial consumption of the O2 provided by the ZnO decomposition and, consequently, a Zn excess is generated.
Journal ArticleDOI
Negative U-properties of the oxygen-vacancy in ZnO
D. Pfisterer,Joachim Sann,Detlev M. Hofmann,Bruno K. Meyer,Thomas Frank,Gerhard Pensl,Ramón Tena-Zaera,Jesús Zúñiga-Pérez,C. Martínez-Tomás,Vicente Muñoz-Sanjosé +9 more
TL;DR: In this paper, the intensity of the oxygen vacancy (VO) related emission in ZnO at 2.45 eV correlates to the concentration of the donor level E4, located 530 meV below the conduction band and attributed to the VO0/++ recharging.
Journal ArticleDOI
Effect of different photoanode nanostructures on the initial charge separation and electron injection process in dye sensitized solar cells: A photophysical study with indoline dyes
Jesús Idígoras,Jan Sobuś,Mariusz Jancelewicz,Eneko Azaceta,Ramón Tena-Zaera,Juan A. Anta,Marcin Ziółek +6 more
TL;DR: In this paper, the performance of ZnO-based photoanode nanostructures and standard TiO2 nanoparticle layers sensitized with the indoline dye coded D358 was investigated.
Journal ArticleDOI
Nanophotoactivity of Porphyrin Functionalized Polycrystalline ZnO Films.
Celia Rogero,David F. Pickup,Jaime Colchero,Eneko Azaceta,Ramón Tena-Zaera,Elisa Palacios-Lidón +5 more
TL;DR: Kelvin probe force microscopy in darkness and under illumination is reported to provide nanoscale-resolved surface photovoltage maps of hybrid materials and reveals the complexity of real device architectures with ill-defined surfaces even in a relatively simple system.
Journal ArticleDOI
Ionic liquid-based electrodeposition of ZnS:nano-MoS2 composite films with self-lubricating properties
TL;DR: In this article, an innovative protocol to electrodeposit ZnS:nano-MoS2 composite coatings with enhanced tribological properties is reported, and the mechanisms involved in the deposition process are analyzed by cyclic voltammetry.
