Therefore, the accuracy of those values is not very high. However, the large differences allowed a good differentiation from carbon. No

The differential barrier, Φdiff, may be thought of as similar to the commonly used apparent barrier height defined by Φapp = (∂zI/I)2, which is bias dependent. Due to differentiation, however, Φdiff is much more sensitive to changes in
