A linear-chain model with variable force constants for the couplings at heterojunctiorts is used to calculate the spectrum of confined longitudinal-optical (LO) phonon frequencies in a short-period strained-layer superlattice. Even for the case of a superlattice with only two atomic monolayers in ea
AbstractΓIt is well known that impurities in iron which segregate to grain boundaries can dramatically change physical properties. Carbon and boron tend to increase ductility while phosphorous and sulphur lead to embrittlement. Cohesion at boundaries in iron can be understood by studying changes in
