    Phosphorus was first made by Hennig Brandt at Hamburg in 1669 when he evaporated urine and heated the residue until it was red hot, whereupon phosphorus vapour distilled which he collected by condensing it in water. Brandt kept his discovery secret, thinking he had discovered the Philosopher's Stone that could turn base metals into gold.

  • Laser annealing for n+/p junction formation in germanium ...

    Abstract In the present work we focus our study on laser annealing of implanted with high phosphorus dose p-type germanium wafers using an Nd-YAG laser at 355 nm. Dopant profiles as monitored by SIMS measurements demonstrate dopant profile movement less than 15 nm at junction depth. Germanium (Ge) structural defects were observed by TEM measurements and the roughness of the surface was ...

  • Raman investigation of germanium- and phosphorus-doping ...

    It is shown that phosphorus has a much more sensitive effect on the glassy structure than germanium, both at small and medium scales. Indeed, in the low-wavenumber region (7100 cm1), the phosphorus-doping was found to affect the intensity of the boson peak, suggesting an enhancement of heterogeneity at the nanometer scale.
