WebThe sheet resistance (σ) is calculated as follows: where: σ = the sheet resistance (Ω/square or just Ω) Note that the units for sheet resistance are expressed in terms of Ω/square in order to distinguish this number from the measured resistance (V/I). Using the Kelvin Technique to Eliminate Lead and Contact Resistance 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.
