Pérez, E. ; Dueñas, S. ; Castán, H. ; García, H. ; Bailón, L. ; Montero, Daniel ; García Hernansanz, Rodrigo ; García Hemme, Eric ; Olea Ariza, Javier ; González Díaz, Germán | American Institute of Physics | 2015-12-28The energy levels created in supersaturated n-type silicon substrates with titanium implantation in the attempt to create an intermediate band in their band-gap are studied in detail. Two titanium ion implantation doses (1013 cm-2 and 1014 cm-2)[...]texto impreso
Nuñez Cascajero, A. ; Blasco, R. ; Valdueza Felip, Sirona ; Montero, Daniel ; Olea Ariza, Javier ; Naranjo, F. B. | Elsevier Science Ltd | 2019-09High-quality Al0.37In0.63N layers have been grown by reactive radio-frequency (RF) sputtering on sapphire, glass and Si (111) at low substrate temperature (from room temperature to 300 degrees C). Their structural, chemical and optical propertie[...]texto impreso
Blasco, Rodrigo ; Valdueza-Felip, Sirona ; Montero, Daniel ; Olea Ariza, Javier ; Naranjo, Fernando B | Wiley-VCH Verlag GmbH & Co. KGaA. | 2020Radio frequency sputtering is a low-cost technique for the deposition of large-area single-phase AlInN on silicon layers with application in photovoltaic devices. Here we study the effect of the Al mole fraction x from 0 to 0.56 on the structura[...]texto impreso
Olea Ariza, Javier ; Algaidy, S. ; Prado Millán, Álvaro del ; García Hemme, Eric ; García Hernansanz, Rodrigo ; Montero, Daniel ; Caudevilla Gutiérrez, Daniel ; González Díaz, Germán ; Soria, E. ; Gonzalo, J. | Elsevier Science SA | 2020-04-15We have fabricated GaP supersaturated with Ti by means of ion implantation and pulsed-laser melting to obtain an intermediate band material with applications in photovoltaics. This material has a strong sheet photoconductance at energies below t[...]texto impreso
González Díaz, Germán ; Pastor, D. ; García Hemme, Eric ; Montero, Daniel ; García Hernansanz, Rodrigo ; Olea Ariza, Javier ; Prado Millán, Álvaro del ; San Andres Serrano, Enrique ; Mártil de la Plaza, Ignacio | Elsevier Sci. Ltd | 2017-02The van der Pauw method to calculate the sheet resistance and the mobility of a semiconductor is a pervasive technique both in the microelectronics industry and in the condensed matter science field. There are hundreds of papers dealing with the[...]
