Claim Text:
1. A multigate field-effect transistor device comprising: a gate structure that envelops a plurality of surfaces of at least one fin that are above a substrate; and the at least one fin, wherein the at least one fin provides a channel between a source and the gate structure and between a drain and the gate structure, the at least one fin having a maximum dimension of 30 nm, wherein the at least one fin is composed of a semiconducting material and at least one monolayer of dopant atoms that conformally overlays the semiconducting material in three-dimensions so a conformal thickness of 5 nm or less of said at least one monolayer of dopant atoms is present on an upper surface and sidewall surfaces of the at least one fin, wherein a lattice structure of the at least one monolayer of dopant atoms substantially match a lattice structure of the semiconductor material; and wherein the at least one monolayer of dopant atoms includes at least 4×10
