Available in PDF, EPUB and Kindle. Book excerpt: A pilot line for the production of large high quality ZnO single crystals was established and many large crystals were produced. The pilot line can be divided into two units, (1) a molten salt line for the production of seed plates to be used in (2) the hydrothermal crystal growth pilot line. The design and construction of both lines were successfully completed and functioned as planned. The molten salt crystal growth effort was not as successful as had been anticipated. Large area, high quality crystals could not be made reproducibly by this technique. The most apparent reasons for the failure to do so rests in thermal gradient control during the growth cycle and/or the presence of impurities. Although these problems were not completely resolved the molten salt pilot line did yield sufficient plates for the initial portion of the hydrothermal pilot line, and hydrothermally grown crystals were sectioned and used as seeds for subsequent runs. The area of the crystals were increased by continued growth until large high quality crystals weighting more than 150 grams could be grown on such seeds within reasonable operating times.

This book was released on 2005-12-28 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, a significant effort has been devoted to the investigation of ZnO as a suitable semiconductor for UV light-emitting diodes, lasers, and detectors and hetero-substrates for GaN. Research is driven not only by the technological requirements of state-of-the-art applications but also by the lack of a fundamental understanding of growth processes, the role of intrinsic defects and dopants, and the properties of hydrogen. The NATO Advanced Research Workshop on “Zinc oxide as a material for micro- and optoelectronic applications”, held from June 23 to June 25 2004 in St. Petersburg, Russia, was organized accordingly and started with the growth of ZnO. A variety of growth methods for bulk and layer growth were discussed. These techniques comprised growth methods such as closed space vapor transport (CSVT), metal-organic chemical vapor deposition, reactive ion sputtering, and pulsed laser deposition. From a structural point of view using these growth techniques ZnO can be fabricated ranging from single crystalline bulk material to polycrystalline ZnO and nanowhiskers. A major aspect of the ZnO growth is doping. n-type doping is relatively easy to accomplish with elements such al Al or Ga. At room temperature single crystal ZnO exhibits a resistivity of about 0. 3 -cm, an electron mobility of 2 17 -3 225 cm /Vs, and a carrier concentration of 10 cm . In n-type ZnO two shallow donors are observable with activation energies of 30 – 40 meV and 60 – 70 meV.

This book was released on 2011-03-23 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zinc Oxide (ZnO) powder has been widely used as a white paint pigment and industrial processing chemical for nearly 150 years. However, following a rediscovery of ZnO and its potential applications in the 1950s, science and industry alike began to realize that ZnO had many interesting novel properties that were worthy of further investigation. ZnO is a leading candidate for the next generation of electronics, and its biocompatibility makes it viable for medical devices. This book covers recent advances including crystal growth, processing and doping and also discusses the problems and issues that seem to be impeding the commercialization of devices. Topics include: Energy band structure and spintronics Fundamental optical and electronic properties Electronic contacts of ZnO Growth of ZnO crystals and substrates Ultraviolet photodetectors ZnO quantum wells Zinc Oxide Materials for Electronic and Optoelectronic Device Applications is ideal for university, government, and industrial research and development laboratories, particularly those engaged in ZnO and related materials research.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this investigati on is the elucidation of the electronic energy band structure of zinc oxide and related wurtzite-type crystals, including alloys of zinc oxide and zinc sulfide; zinc sulfide; zinc selenide; and zinc telluride. The principal features of the band structures of these crystals will be determined, and these features will be related to important optical and electronic properties. An attempt will be made to understand the systematic variation of band structure with chemical composition in the sequence ZnO, ZnS, ZnSe, ZnTe, as well as the relationship between the band structures of the cubic and hexagonal modifications of a crystal such as ZnS.
