摘要：
The initial atomic-layer-chemical-vapor-deposition growth of titanium dioxide from TiCl4 and water on quartz glass substrates is monitored in real time by incremental dielectric reflection. An interesting means for bringing the growth from the very beginning into a time-homogeneous mode is proposed and preliminarily studied. It consists in an in situ TiCl4-treatment procedure. The crystal structure and surface morphology of the prepared ultrathin films are characterized.
