Abstract
A system and a method for passivating a surface of a semiconductor. The method includes providing the surface of the semiconductor to a reaction chamber of a reactor, exposing the surface of the semiconductor to a gas-phase metal containing precursor in the reaction chamber and exposing the surface of the semiconductor to a gas-phase chalcogenide containing precursor. The methods also include passivating the surface of the semiconductor using the gas-phase metal containing precursor and the gas-phase chalcogenide containing precursor to form a passivated surface. The system for passivating a surface of a semiconductor may include a reactor, a metal containing precursor source fluidly coupled to the reactor, and a chalcogenide containing precursor source fluidly couple to the reactor, wherein the metal containing precursor source provides a gas-phase metal containing precursor to a reaction chamber of the reactor, and wherein the chalcogenide containing precursor source provides a gas-phase chalcogenide containing precursor to a reaction chamber of the reactor.
