Liquid phase epitaxial growth and heterointerface characteristics of long-wavelength indium gallium arsenide phosphide heterostructures
… (TEM) data are presented that characterize the interfacial ""damage"" that arises during the liquid phase epitaxial growth of an arsenic-poor InGaAsP quatenary on a previously grown iv arsenic-rich layer. This ""damage"" takes the form of a ragged heterointerface with extensive dislocations and …

Solvent-based self-healing approaches for fiber-reinforced composites
Damage in composite materials spans many length scales and is often difficult to detect or costly to repair. The incorporation of self-healing functionality in composite materials has the potential to greatly extend material lifetime and reliability. Although there has been remarkable progress in …
