Investigators at Graduate School Report Findings in Zinc Oxide Nanotechnology

June 6, 2014



By a News Reporter-Staff News Editor at Science Letter -- Research findings on Nanotechnology are discussed in a new report. According to news reporting out of Beijing, People's Republic of China, by NewsRx editors, research stated, "The ZnO films have been prepared by a variable electric field-assisted atomic layer deposition method( ALD). By applying electric fields during the precursor pulses, we can modulate both the crystal orientation and structure of the obtained ZnO films."

Our news journalists obtained a quote from the research from Graduate School, "The ZnO films with c-axis preferred orientation and the least oxygen vacancy defect were obtained when the holder electric polarities were positive and negative during the DEZn and H2O pulse, respectively. It is supported that when electric field was applied in the chamber, the torque may lead to the precursor molecular alignments along the electric field direction, which could affect the film growth process and then influence their structures and properties."

According to the news editors, the research concluded: "This variable electric field-assisted ALD approach would provide an efficient protocol for the growth of semiconductor films with designed properties."
