In this thesis, the structural, optical, and electrical properties of wurtzite MgxZn1-xO:Al and MgxZn1-xO:Ga thin films have been investigated in dependence on Mg and dopant concentration. Among the transparent conductive oxides (TCOs), ZnO based compounds have gained renewed interest as a transparent electrode for large scale applications such as defroster windows, at panel displays, touch screens, and thin film solar cells due to low material and processing cost, non-toxicity, and suitable physical properties. In general, these applications require transparent electrodes with lowest possible

Abstract:

This thesis investigates two variations of the conventional pulsed laser deposition (PLD) technique. The first technique is femtosecond PLD, whereby the laser used to ablate the target has a significantly higher peak intensity and shorter pulse duration as compared to conventional nanosecond lasers more commonly used for PLD. Experiments have been conducted on the growth of Nd:Gd is presented. Experimental results will show the composition and lattice parameter of a film can be controlled by changing the relative laser fluences on the two targets. Films have been grown with enough extra Ga to

Abstract:

This thesis introduces a novel deposition technique, Plasma-Enhanced Pulsed Laser Deposition (PE-PLD) that attempts to overcome limitations in traditional PLD by combining it with a background oxygen RF plasma instead of a neutral gas. Advantages of this novel technique for the deposition of metal-oxide films include, the use of simple, pure metal targets instead of metal-oxide composite targets and the lack of the necessity for substrate heating and post-annealing to obtain high-quality films. The feasibility of this method was studied both numerically and experimentally. Numerical simulation

Pulsed laser deposition (PLD) was used to deposit hydroxyapatite (HA) thin films on various substrates, including silicon (100) and titanium (Ti-6Al-4V) alloy. Thin films of amorphous HA were deposited at room temperature and then annealed over a range of temperatures. The microstructure and composition of the films were determined using scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDS), and X-ray diffraction (XRD). The HA films were found to achieve total crystallinity at 350㮠The mechanical properties of the films were studied by means of nanoindentation and scrat

ZnO thin films and nanostructures were grown by eclipse pulsed laser deposition (EPLD) for the first time. On bare sapphire held at 600 °C, a complex nanostructured surface was formed when ablating a metallic Zn target in an oxygen ambient. Nanorods grown by a vapor-solid mechanism clumped together in well separated, micron-sized regions. Nanoscale pyramids with 6 fold symmetry formed between the nanorod clumps by vapor-liquid-solid growth. Strong photoluminescence (PL) was observed from the EPLD grown samples, an order of magnitude stronger than PLD grown nanorods formed under similar growth

There are many applications for small scale, solid state lasers in the near infrared, where conversely there are very few such devices. A lasing device in a rare earth doped gallium-lanthanum-sulphide thin film is attractive due to emission at wavelengths in the 2 to 5 µm region where many gasses and liquids have fundamental vibrations and overtones and so are detectable. This region also covers the 3 to 5 µm atmospheric 'windows'. Some examples of such detection is presented in this thesis.

Planar waveguides are of interest because of the implications of their structure, which allows for lasing, pumping and heat dissipation to each have a unique axis of operation, and the confinement properties of planar waveguide lasers result in lower pump power thresholds, higher gains per unit pump power and higher efficiencies than their bulk counterparts.

Im ersten Teil wird die Methode, welche vertical continuous composition spread (VCCS) PLD genannt wird, eingeführt und am MgxZn1−xO Legierungssystem erprobt. Die Methode erlaubt die Kontr

碩士<br>東海大學<br>物理學系<br>95<br>The bulk Ce3Al11 undergoes a ferromagnetic transition at Tc=6.2K, follow by an antiferromagnetic ordering at TN=3.2K.This research, we develop a Pulsed Laser Deposition System which working with a Nd:YAG laser. Ce3Al11 were fabricated by controlling the distance between substrate and target with different gas and wavelength of laser. The sizes of nanoparticles were checked by TEM and SEM. We find the distance between target and substrate is main factor to change the size of nanoparticle. The Liquid-Pulsed-Laser(LPLD) process is also developed to fabricate the partic

碩士<br>國立臺北科技大學<br>光電工程系研究所<br>97<br>In this study, thin films of cuprous oxide were deposited on Al2O3 substrates by pulsed laser deposition technique. An Nd:YAG Q-switched laser operating at a wavelength of 266nm, a pulsed duration less than 10ns, and a repetition rate of 10Hz, was used to ablate a Cu2O target. The Target for the deposition was obtained by sintering high-purity CuO powder(99.999%) at 1000℃ for 5 hours. The effects of the growth parameters on the film morphology, roughness, crystallinity, and optical properties were systematically investigated. In addition, the effects of the

碩士<br>國立中央大學<br>物理研究所<br>98<br>For single crystal Fe57BO3 and single crystal Fe57CO3, there is the character of Storage of Nuclear Excitation Energy in Fe57BO3 through Magnetic Switching and the character of electromagnetically induced transparency of hard X‐ray pulse in 57FeCO3 by nuclear level mixing of nucleus separately. F or the development of lasing without inversion, the characters are very important. So we need to research single crystal Fe57BO3 and single crystal Fe57CO3. We need to make the polycrystal Fe57BO3 and polycrystal Fe57CO3 if we want to make the single crystal Fe57BO3 and
