These three elements are highly soluble in silicon with solubilities exceeding 5 x 1020 atoms cm3 in the diffusion temperature range (between 800oC and 1200oC). These dopants can be introduced via several means, including solid sources (BN for B, As 2 O 3 for As, and P 2 O 5 for P), liquid sources (BBr 3

    Bearings are used to prevent friction between parts during relative movement. In machinery they fall into two primary categories: anti-friction or rolling element bearings and hydrodynamic journal bearings. The primary function of a bearing is to carry load between a rotor and the case with as little wear as possible.
