Abstract
We have demonstrated that phosphorus delta-doping of germanium in ultra-high vacuum is a promising technique to tune doping at high densities (>1020 cm-3) in thin Ge films. Eventually, high doping densities on demand for photonic or electronic applications may be delivered by suitably choosing the total number of layers, tuning their separation in the δ-layer stack, and engineering the amount of P incorporated in each layer.
