Available in PDF, EPUB and Kindle. Book excerpt: This Thesis has been focused on the fabrication and characterization of different CMOS- compatible materials in order to determine both their electro-optical and resistive switching properties. Basically, two materials have been explored, silicon-aluminum oxynitride (SiAlON) and zinc oxide (ZnO). The first material under study, SiAlON, has been fabricated using three techniques, namely RF-sputtering, pulsed-laser deposition and electron beam evaporation. In this case, different stoichiometries were analyzed in order to obtain excellent optical and electrical properties. The incorporation of different rare earths (REs) was also carried out, using Ce and Eu, which exhibited photoluminescence (PL) emission under laser excitation. The electro-optical characterization was performed after fabricating device structures onto p-type silicon substrates. The employed top electrode was selected depending on the characterization technique. To collect the electroluminescence (EL) from the devices a transparent conductive oxide (TCO) was required, using indium tin oxide (ITO) because of its excellent electrical and optical properties. Light emission was obtained from both devices, containing Ce and Eu, suggesting that SiAlON is a great candidate to be employed as RE host matrix. In addition, the resistive switching properties of these devices were analyzed as well, using Al as top electrical contact. Similar fabrication processes were carried out towards attaining rare earth (RE)-doped SiAlON. This was achieved by depositing a multilayered structure of Tb-Al/SiO2, which allowed determining the RE ions inclusion effectivity of the delta-doping approach. The optical characterization demonstrated PL emission from trivalent Tb3+ ions. Different (Al/Tb/SiO2) multilayer configurations were tested to optimize the number of active luminescent centers. Finally, the resistive switching properties of RE-doped SiO2 were also analyzed and the role of the RE ions within was explored as well. The second studied material was ZnO. In this case, the material was deposited onto p- type silicon via either RF-sputtering or atomic layer deposition (ALD) depending on the role of the deposited layer. While the first one was used to deposit the ZnO as RE host matrix, the second one was employed to attain a ZnO layer acting as TCO top electrode. In the first case, different REs (Tb and Eu) were tested. A clear PL emission of both REs was obtained. The narrow peak-like features in the spectra indicate the optical activation of the trivalent RE ions, being the ZnO an optimum host matrix for this kind of luminescent centers. To carry out the electrical characterization, device structures were attained using ITO as top TCO electrode. The EL from these devices was obtained, achieving similar spectra than the ones observed via PL. However, the luminescent degradation with time suggests the formation of conductive paths which effectively quench the EL emission. Taking into account this behavior, the resistive switching properties of these devices were analyzed, obtaining different cycles. The role of the REs in the resistive switching properties of ZnO was studied as well, allowing for a reduction of the current compliance in the electroforming process, but increasing the required voltages to induce the resistive switching phenomenon. Moreover, the incorporation of the REs into the ZnO host matrix permitted obtaining more stable Reset processes, which suggests that the REs near the conductive paths could trap part of the out-diffused oxygen ions and, consequently, the re-oxidation of these conductive paths becomes easier. Finally, when using a ZnO layer as top electrical contact, a multilayered SiOx/SiO2 structure was employed. After deposition, this structure was annealed at high temperature in order to induce the precipitation and crystallization of the silicon excess in the form of silicon nanocrystals (Si-NCs). The optical and electrical properties of these nanostructures are well known and have reported in previous works and doctoral theses of the research group. Therefore, the incorporation of the ZnO as TCO was implemented to determine the EL of the Si-NCs when current is injected under different electrical polarizations. Studies in DC and AC have been carried out, obtaining interesting results related to the modulation of the light emission from ZnO defects and enhancing the EL emission from the Si-NCs. The incorporation of a thin Si3N4 inversion layer, between the Si substrate and the multilayered Si-NCs, allowed modifying the injected current, thus obtaining an enhancement of the EL emission. These measurements confirmed the good electrical and optical properties of the ZnO working as TCO and permitted to understand the physical mechanisms involved in the EL process of the luminescent centers. In addition, the resistive switching properties of these devices were determined. In this case, devices presented some cycles with well defined resistive states. Under these resistive switching conditions, devices exhibit EL emission, being the intensity and the threshold voltage dependent on the resistive state. In conclusion, the results presented in this Thesis accomplish the initial pursued objectives, demonstrating the correlation between the EL emission and the resistive switching properties. Using these characteristics, the resistive state can be read not only electrically, but also optically from the emission of the luminescent centers through the TCO top electrode contact. Overall, these results pave the way to a new set of memory devices that can be, in a near future, integrated into the Photonics field, dominated by faster interconnections and less dependence to material transmission media.

Available in PDF, EPUB and Kindle. Book excerpt: The world of today must face up to two contradictory energy problems: on the one hand, there is the sharply growing consumer demand in countries such as China and India. On the other hand, natural resources are dwindling. Moreover, many of those countries which still possess substantial gas and oil supplies are politically unstable. As a result, renewable natural energy sources have received great attention. Among these, solar-cell technology is one of the most promising candidates. However, there still remains the problem of the manufacturing costs of such cells. Many attempts have been made to reduce the production costs of conventional solar cells (manufactured from monocrystalline silicon using diffusion methods) by instead using cheaper grades of silicon, and simpler pn-junction fabrication. That is the hero of this book; the heterojunction solar cell.
