This book was released on 2015 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: A versatile home-made atomic layer deposition (ALD) reactor was designed and built in our lab. This reactor can be used to deposit metal oxides on both wafer substrates and porous inorganic particles. Also, a simple procedure for selective ALD has been developed for the processing of silicon wafers in order to facilitate the spatially resolved growth of thin solid films on their surfaces. Specifically, a combination of silylation and UV/ozonolysis was tested as a way to control the concentration of the surface hydroxo groups required for subsequent atomic layer deposition (ALD) of metals or oxides. Water contact angle measurements were used to evaluate the hydrophilicity/hydrophobicity of the surface, a proxy for OH surface coverage, and to optimize the UV/ozonolysis treatment. Silylation with silanes was found to be an efficient way to block the hydroxo sites and to passivate the underlying surface, and UV/O 3 treatments were shown to effectively remove the silylation layer and to regain the surface reactivity. Both O3 and 185 nm UV radiation were determined necessary for the removal of the silylation layer, and additional 254 nm radiation was found to enhance the process. Attenuated total reflection-infrared absorption spectroscopy was employed to assess the success of the silylation and UV/O 3 removal steps, and atomic force microscopy data provided evidence for the retention of the original smoothness of the surface. Selective growth of HfO2 films via TDMAHf + H2 O ALD was seen only on the UV/O3 treated surfaces; total inhibition of the deposition was observed on the untreated silylated surfaces. We believe that the silylation-UV/O 3 procedure advanced here could be easily implemented for the patterning of surfaces in many microelectronic applications.

Download or read book Metal Oxide Thin Films for Solar Energy and Industrial Applications written by Dominic Eya and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thin films of the metallic oxide have a wide variety of applications such as surface acoustic wave devices (SAW), bulk acoustic wave devices (BAW), acoustic-optic devices, micro-electromechanical systems (MEMS), band pass filters, optical wave-guide, and laser deflectors using piezoelectric or piezooptic properties. With appropriate dopants such as aluminium, some of the oxides are electrically conductive and could be employed as transparent conducting electrodes for flat panel displays and solar cells. Due to their unique conducting mechanism based on oxygen vacancies, the oxides are also used in oxygen gas sensors, window layers in copper indium diselenide based heterojunction solar cells, and high temperature solid lubricants in gas turbine engines, and in electro chromic devices. Conducting metal oxide thin films are good infrared detectors, reflectors and are applied as energy efficient window treatments where high infrared reflectance and low thermal emittance are required.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, atomic layer deposition (ALD) has become a popular technique to deposit ultra-thin films with superior conformality and thickness control. Because of its unique surface adsorption-limited mechanism and the resulting capability of deposition at low temperatures and moderate pressures, ALD has found industrial applications in field effect transistor fabrication and coating of multilayer interconnection metallization. In this work, I have explored the potential of ALD-grown metal oxide layers in applications beyond typical electronics technologies. In particular, this research has focused on using ALD-grown metal oxides to enhance the performance and stability in aqueous solutions of biomolecular sensors and semiconducting anodes for photoelectrochemical fuel synthesis. In the biosensing application, we have replaced the SiO2 gate dielectric material typically used in high sensitivity bio-field-effect-transistors (bioFET) with high dielectric constant HfO2. The SiO2 bioFET gate dielectric suffers from poor stability and non-ideal dielectric response at the very small physical thicknesses required to achieve high sensitivity. ALD-grown HfO2, on the other hand, is capable of providing high capacitance density with a physically thicker dielectric layer, thanks to its large dielectric constant. With the ALD-HfO2 gate dielectric, biosensor switching behavior was demonstrated using capacitance-voltage measurements in water, while at the same time maintaining the desired high capacitance. In addition, we have verified bio-functionalization of the HfO2 film surface with biotin molecules via photoelectron spectroscopy, and detected streptavidin and avidin binding with capacitance-voltage analysis and molecular AFM imaging methods respectively. For the solar fuel synthesis, we have studied the behavior of ALD-TiO2 tunnel oxides that can protect heretofore unstable semiconductors, such as Si, used as photoanodes in water splitting. For several decades, intense research effort has been devoted to identifying an efficient photoelectrochemical cell for oxidizing water under solar illumination. The resulting hydrogen and oxygen can be used to store energy from the intermittent terrestrial solar resource renewably, using water as a feedstock. However, photoanode materials choices have always been limited because the water oxidation half reaction at the anode surface is highly corrosive and requires large overpotentials. As a result, only oxidation-stable wide bandgap semiconductors such as TiO2 and Fe2O3 have been used as the photoanode. These photoanodes exhibit poor efficiency, however, because of their large bandgaps. Lower bandgap semiconductors, such as Si, are capable of absorbing solar light much more efficiently, but are easily corroded during water oxidation. In this work, a silicon photoanode was passivated by a thin and pinhole-free layer of ALD-TiO2 such that efficient light absorption in the Si and the chemical stability of the TiO2 can be exploited at the same time. This ALD-grown nanocomposite photoanode has been demonstrated to perform water oxidation with low overpotentials, while at the same time maintaining good stability with hours of continuous operation. The tunneling of electronic carriers through the thin ALD-TiO2, required to sustain high oxidation rates, has also been investigated by varying the TiO2 thickness. The annealing temperature and ambient have also been investigated.
