Claim:
1. A contact on a semiconductive prominence, comprising: a group IV semiconductive substrate; a prominence disposed on the semiconductive substrate, wherein the prominence is a group IV semiconductor; a surface-doped structure comprising a III-V material on the prominence, wherein the III-V material has a larger lattice constant than the group IV semiconductor of the prominence at the interface of the III-V material and the group IV semiconductor of the prominence, wherein the surface-doped structure has a first concentration of a dopant and the prominence has a second concentration of the dopant, and wherein the first concentration of the dopant is different than the second concentration of the dopant; and a contact metallization having a contact metallization contact area coupled to the surface-doped structure, wherein the prominence has a prominence form factor, and wherein the contact metallization contact area reflects the prominence form factor.
