Abstract
An apparatus for carrying out atomic layer epitaxial growth of a thin semiconductor layer on a substrate surface has a cylindrical chamber in which a substrate holder is coaxially mounted so as to define an annular gap therebetween. The substrate holder can be in the form of a rotatable turbine wheel and a funnel-shaped hood introduces a reactant gas onto the substrate at an oblique angle.
