Book Description
Wide direct band gap gallium nitride (GaN) semiconductor has received significant attention as an ideal material for various applications in the optoelectronic devices. One major use of GaN is the development of energy-efficient solid state light-emitting diodes. Currently, most commercially available GaN semiconductor are produced through advanced deposition techniques which involve sophisticated technologies and are relatively expensive and complicated to setup. As an alternative, the sol-gel spin coating method, which is relatively simpler, cheaper, safer, and more scalable was proposed. In this book, the process route and recipe for producing highly c-oriented crystalline GaN thin films via the sol-gel spin coating approach were described in detail. Some insights into the factors affecting the surface morphology as well as structural and optical properties of the deposited films were presented. Eventually, this book could inspire further studies into the development of low-cost GaN thin films.

Book Description
Recently the sol-gel process for preparing amorphous materials has been studied. The low processing temperatures enable us to dope the gel with functional organic molecules. Such molecules have poor thermal stability and cannot be included in traditional oxide glasses. Avnir et al. have been reported the preparation and optical properties of amorphous silica doped with rhodamine 6G and pyrene. Makishima and Tani have doped one with 1,4dihydr-oxy-9,10-anthraquinone (DAQ) and showed photochemical hole burning (PHB) at 4.8 K. They have also demonstrated that other organic molecules can be successfully incorporated into sol-gel matrices. The number of potential applications of such materials is expected to be substantial. Although materials have been synthesized, little is known about the structure of sol-gel matrix and the interaction between the molecule and the matrix. PHB has attracted considerable interest as a tool for high-resolution solid state spectroscopy. The sol-gel thin film is expected to possess several advantages over gel bulks. Several studies suggest the differences of the structure and properties between bulks and thin films. However, due to the thickness, there have been rather few investigations attempting to obtain structural information directly. Recently the use of organic molecule appears to be one approach for supplying new insights regarding the chemistry of sol-gel materials. In this point of view PHB is expected to be high potential. We report here the preparation of sol-gel thin films doped with the porphine derivative and its application to PHB.
