Exemplary deposition methods may include delivering a boron-containing precursor to a processing region of a semiconductor processing chamber. The methods may include delivering a dopant-containing precursor with the boron-containing precursor. The dopant-containing precursor may include a metal. The methods may include forming a plasma of all precursors within the processing region of the semiconductor processing chamber. The methods may include depositing a doped-boron material on a substrate disposed within the processing region of the semiconductor processing chamber. The doped-boron material may include greater than or about 80 at. % of boron in the doped-boron material.
