Matching Conditions in Effective-Mass Theory
Walter A. Harrison
It has been shown that the traditional matching of wavefunctions between regions of different effective mass (matching ψ and (1/m*)\partialψ/\partialx) is not correct, but that one…
The origin of Sr segregation at La1-xSrxMnO3 surfaces
Walter A. Harrison
A uniform distribution of La and Sr in lanthanum-strontium manganites would lead to charged crystal planes, a charged surface, and arbitrarily large surface energy for a bulk cryst…
Oxygen atoms and molecules at Lanthanum-Strontium Manganite surfaces
Walter A. Harrison
A localized description, rather than energy bands, is appropriate for the manganite substrate. Empty substrate levels lower in energy than occupied oxygen levels indicate need for…
Tight-binding theory of lanthanum strontium manganate
Walter A. Harrison
An earlier analysis of manganese oxides in various charge states indicated that free-atom term values and universal coupling gave a reasonable account of the cohesion. This approac…
Tight-Binding Theory of Manganese and Iron Oxides
Walter A. Harrison
The electronic structure is found to be understandable in terms of free-atom term values and universal interorbital coupling parameters, since self-consistent tight-binding calcula…
Heisenberg exchange in magnetic monoxides
Walter A. Harrison
The superexchange intertacion in transition-metal oxides, proposed initially by Anderson in 1950, is treated using contemporary tight-binding theory and existing parameters. We fin…
