Image force effects
Web8 dec. 1999 · The effect of an image force on the barrier for the injection of the carrier from the electrode into the organic layer is shown to be essential for proper understanding of the metal/organic contact and, in particular, of recent results of internal photoemission experiments for metal/Alq 3 interfaces. Web29 jan. 2024 · A new analysis method of reverse leakage current for β-Ga 2 O 3 Schottky barrier diodes is performed by using two models: bias dependence and no bias dependence of barrier height. The method incorporates both the current induced by the tunneling of carriers through the Schottky barrier and the current induced by the thermionic emission …

A unique simulation cell shape is found to minimize spurious image effects for a fixed simulation volume (i.e. fixed total number of atoms) and specified initial dislocation line length. The results are used to estimate image stress effects in various literature studies involving dislocation bow-out. The imageeffectsarenon-negligible.
Web23 apr. 2012 · By using first-principles calculations and classical image force model, we studied the image force induced Schottky barrier (SB) height reduction in carbon nanotube (CNT)-metal contact. A low dielectric constant leads to a stronger band bending and therefore strongly reduces the SB height. This reduction depends on carrier … WebThe image of an electric point dipole is a bit more complicated. If the dipole is pictured …
Due to the image force effect depends highly on the distance from the charge to the metal surface, i.e., the magnitude of the force is inversely proportional to this distance, it can be negligible when nitrogen atoms are away from the substrate compared to the case that they are close to the substrate.
