Fermi-level pinning factor

WebIn this work, the neutrality level (the average pinning position of Fermi level) was determined as 0.661 eV below the conduction band. These values has been cal-culated as 6 ·1013 1/eV per cm2 and 0.55 eV for p-GaAS [33]. In addition, the parameter S and the average pin-ning position of the Fermi level can be calculated by replacing the φ WebWe would like to show you a description here but the site won’t allow us.
