Abstract
Methods for depositing silicon include cycling dosing between 1 and 100 cycles of one or more first chlorosilane precursors on a III-V surface at a temperature between 300° C. and 500° C. to form a first layer. Methods may include desorbing chlorine from the first layer by treating the first layer with atomic hydrogen to form a second layer. Methods may include forming a silicon multilayer on the second layer by cycling dosing between 1 and 100 cycles of one or more second chlorosilane precursors and atomic hydrogen at a temperature between 300° C. and 500° C. A layered composition includes a first layer selected from the group consisting of InGaAs, InGaSb, InGaN, SiGe, and Ge, wherein X is between 0.1 and 0.99, and a second layer, wherein the second layer comprises Si—H and Si—OH.
