Abstract:
1. A method for producing a doped material of desired composition and thickness comprising the steps of: selecting a surface functionalization species; growing a first thickness of a host matrix material; dosing a surface functionalization species for controlling dopant wherein the surface functionalization species is chemically different than the host matrix and a dopant precursor and the surface functionalization species being non-reactive with the dopant precursor; and dosing the dopant precursor and wherein the surface functionalization species dose acts as a control for limiting precursor deposition on the first thickness of host matrix; dosing a dopant precursor co-reactant forming dopant on a portion of the host matrix; dosing a surface functionalization species co-reactant to react with the surface functionalization species to obtain a desired surface chemistry for deposition of one or more additional layers of host matrix material thereby obtaining the doped material.
