Alonso Orts, Manuel ; Sánchez, A. M. ; López, I. ; Nogales Díaz, Emilio ; Piqueras de Noriega, Javier ; Méndez Martín, Bianchi | RSC Royal Society of Chemistry | 2017-11-07In this work, a simple thermal evaporation method has been used to obtain a variety of Ga?O?/SnO? nano-assemblies with different shapes and dimensionalities, which may affect their physical properties, especially those influenced by surface prop[...]texto impreso
Alonso Orts, Manuel ; Nogales Díaz, Emilio ; Méndez Martín, Bianchi ; Rigby, Oliver M. ; Stamp, Alice V. ; Hindmarsh, Steve A. ; Sánchez, Ana M. | IOP Publishing | 2019-02-01beta-Ga_2O_3 intergrowths have been revealed in the SnO_2 rutile structure when SnO_2/Ga_2O_3 complex nanostructures are grown by thermal evaporation with a catalyst-free basis method. The structure is formed by a Ga_2O_3 nanowire trunk, around [...]texto impreso
Alonso Orts, Manuel ; Nogales Díaz, Emilio ; San Juan, José M. ; Nó, Maria L. ; Méndez Martín, Bianchi | SPIE | 2019On one hand, interest on the tunability of the optical microcavities has increased in the last few years due to the need for selective nano-and microscale light sources to be used as photonic building blocks in several applications. On the other[...]texto impreso
López, I ; Alonso Orts, Manuel ; Nogales Díaz, Emilio ; Méndez Martín, Bianchi ; Piqueras de Noriega, Javier | IOP publishing ltd | 2016-11Gallium oxide microrods have been grown by an evaporation-deposition method by using a precursor containing lithium in order to check the influence of such dopant on the morphology and physical properties of the obtained ß-Ga_2O_3 structures. SE[...]texto impreso
Peres, Marco ; Fernandes, A.J.S. ; Oliveira, F.J. ; Alves, L.C. ; Alves, E. ; Monteiro, T.S. ; Cardoso, S. ; Alonso Orts, Manuel ; Nogales Díaz, Emilio ; Méndez Martín, Bianchi | Electrochemical Society | 2019-06-24A thermal actuator based on thin flexible lamellas of Ga_2O_3 was designed in order to demonstrate the potential of this semiconductor for micro-opto-electro-mechanical applications (MOEMs). The working principle of these devices is based on the[...]texto impreso
Alonso Orts, Manuel ; Nogales Díaz, Emilio ; San Juan, J. M. ; Nó, M. L. ; Piqueras de Noriega, Javier ; Méndez Martín, Bianchi | Amer Physical Soc | 2018-06-07Optical microcavities are key elements in many photonic devices, and those based on distributed Bragg reflectors (DBRs) enhance dramatically the end reflectivity, allowing for higher quality factors and finesse values. Besides, they allow for wi[...]texto impreso
Alonso Orts, Manuel ; Chilla, Gerwin ; Hötzel, Rudolfo ; Nogales Díaz, Emilio ; San Juan, José M. ; Nó, Maria L. ; Eickhoff, Martin ; Méndez Martín, Bianchi | Optical Society of America | 2021-01-15In this Letter, we report optical confinement in the near-ultraviolet (near-UV) range in Ga2O3 nanowires (NWs) by distributed Bragg reflector (DBR) nanopatterned cavities. High-contrast DBRs, which act as the end mirrors of the cavities of the d[...]texto impreso
Alonso Orts, Manuel ; Sanchez, Ana M ; Hindmarsh, Steven A ; López, Iñaki ; Nogales Díaz, Emilio ; Piqueras de Noriega, Javier ; Méndez Martín, Bianchi | Amer Chemical Soc | 2017-01-11Tailoring the shape of complex nanostructures requires control of the growth process. In this work, we report on the selective growth of nanostructured tin oxide on gallium oxide nanowires leading to the formation of SnO_2/Ga_2O_3 complex nanost[...]texto impreso
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[...]
