Abstract
For the use of hydrothermally grown crystals in optoelectronic device applications, improved crystallinity and better control of resistivity are required. Resistivity depends on structural defects and impurities. Hydrothermal synthesis allows the mass production of ZnO single crystals at low cost. However, ZnO single crystals grown by this method still have impurities and defects. The green-yellow spectral emission observed in ZnO at room temperature is believed to be caused by defects and is attributed to the presence of oxygen vacancies or zinc interstitial atoms, but the cause is still unknown. We have cut a-plane, m-plane, and c-plane substrates from hydrothermally grown ZnO bulk single crystals and identified and studied the defects and impurities by electron spin resonance (ESR), luminescence lifetime, photoluminescence (PL), X-ray diffraction (XRD) and energy-dispersive X-ray spectroscopy (EDS).
期刊介绍：
The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
