In real semiconductor heterojunctions, Anderson's rule fails to predict actual band offsets. In Anderson's idealized model the materials are assumed to behave as they would in the limit of a large vacuum separation, yet where the vacuum separation is taken to zero. It is that assumption that involves the use of the vacuum electron affinity parameter, even in a solidly filled junction where there is no vacuum. Much like with the Schottky–Mott rule, Anderson's rule ignores the real chemical … Web1 day ago · Solubilized membranes were centrifuged for 40 min at 186,000g, then slowly passed over high-capacity Strep-Tactin (IBA) affinity resin at flow rate of 0.8 ml min −1.
