How is resistance measured and abbreviated
Web15 aug. 2024 · Resistivity ρ is an intrinsic property of a material, independent of its shape or size. The resistance R of a uniform cylinder of length L, of cross-sectional area A, and made of a material with resistivity ρ, is (8.4.1) R = ρ L A. The table below gives representative values of ρ. WebThe contact resistance Rcontact is abbreviated as RC in the figures. Using the transfer characteristics measured before and after the electrical stress, we found that the contact resistance improved (reduced from 200 kΩ to 90 kΩ), while the carrier mobility increased from 3600 V 2 ·cm −1 ·s −1 to 3900 V 2 ·cm −1 ·s −1.
