Description
Summary:Strained-layer superlattice structures grown in the InGaAs/InP system have turned out to be ideal model systems to study fundamental problems in materials science and metallurgy. We have used them to investigate how metals can be made stronger at high temperature yet retain ductility at low temperature, how a desirable microstructure may be made stable at high temperature, and why materials are stronger under very high strain gradients.
