WebbSharvin Resistance = 4ρL/3πa2 (3) DISCUSSION On silicon, SSRM requires a sufficient load (10-12 Gpa) to produce a pressure induced phase transformation to the metallic β-tin phase of silicon. The high pressures involved require the use of a conductive solid diamond or a diamond coated probe. Webbsion for the resistance of a contact: R 4ρl/πd2. The integration over all possible angles gives a numerical factor 4/3 leading to the Sharvin resistance of a circular contact: R Sh = 16ρl 3πd2.
