摘要

From studies on the epitaxial growth of CeO_2 layers on Si(100) substrates using reactive DC magnetron sputtering, it has been found that the epitaxial CeO_2 layer with (100) or (110) orientation is selectively grown by controlling substrate bias and the growth rate. Optimum bias for the CeO_2(100) layer growth was ±15 V. In order to develop this technology into two-dimensional orientation selectivity, we attempt to grow CeO_2(100) by low energy electron irradiation, as an alternative way to substrate bias application. It proved that electron beams in two energy regions of 30-40 and 80-100eV are effective on preferential growth of CeO_2(100) layers.
