Méndez Martín, Bianchi ; López, I. ; Alonso Orts, Manuel ; Sanz, A. ; Nogales Díaz, Emilio ; Hidalgo Alcalde, Pedro ; Piqueras de Noriega, Javier | Spie-Int Soc Optical Engineering | 2017-05-30The synthesis of complex nanostructures that combine materials and dimensionality, promises the ability to identify novel designs and architectures with enhanced properties that could be used in new devices. One of the building blocks in nanomat[...]texto impreso
López García, Iñaki ; Cebriano Ramírez, Teresa ; Hidalgo Alcalde, Pedro ; Nogales Díaz, Emilio ; Piqueras de Noriega, Javier ; Méndez Martín, Bianchi | American Institute of Materials Science (AIMS) | 2016A thermal evaporation method developed in the research group enables to grow and design several morphologies of semiconducting oxide nanostructures, such as Ga_2O_3, GeO_2 or Sb_2O_3, among others, and some ternary oxide compounds (ZnGa_2O_4, Zn[...]texto impreso
Herein, we report the influence of the surface conditions on the cathodoluminescence (CL) emissions from Zn_2GeO_4 nanowires and Zn_2GeO_4/SnO_2 heterostructures obtained by thermal evaporation technique. A Zn_2GeO_4 nanowire surrounded by a dis[...]texto impreso
Alemán, B. ; Hidalgo Alcalde, Pedro ; Fernández Sánchez, Paloma ; Piqueras de Noriega, Javier | IOP publishing ltd | 2009-11-21Bi doped ZnO nanowires and rods have been grown by a catalyst free evaporation-deposition method with precursors containing either ZnO and Bi_2O_3 or ZnS and Bi_2O_3 powders. The use of ZnS as a precursor was found to lead to a higher density of[...]texto impreso

Dolado Fernández, Jaime ; Martínez Casado, Ruth ; Hidalgo Alcalde, Pedro ; Gutiérrez, Rafael ; Dianat, Arezoo ; Cuniberti, Gianaurelio ; Domínguez-Adame Acosta, Francisco ; Díaz García, Elena ; Méndez Martín, Bianchi | Pergamon-Elsevier Science Ltd | 2020-09-01Achieving efficient and stable ultraviolet emission is a challenging goal in optoelectronic devices. Herein, we investigate the UV luminescence of zinc germanate Zn_2GeO_4 microwires by means of photoluminescence measurements as a function of te[...]texto impreso
Dolado Fernández, Jaime ; Renforth, Kate L. ; Nunn, James E ; Hindsmarsh, Steve A. ; Hidalgo Alcalde, Pedro ; Sánchez, Ana M. ; Méndez Martín, Bianchi | American Chemical Society | 2020-01Herein, we report the formation of a particular core-shell structure, with a zinc germanate (Zn_2GeO_4) nanowire core and a discontinuous shell of SnO_2 nanocrystals, obtained in a single-step process. We propose a growth model that combines the[...]
