Phase transitions in isolated molecules
Abstract It is shown that an isolated polyatomic molecule can undergo a structural phase transition when optically pumped.
General trends in In surface segregation during MOVPE of InGaN-based heterostructures are considered in terms of a rate-equation model. A parametric study of segregation effects is carried out with reference to a single GaN/InGaN/GaN quantum well. The theoretical predictions are compared with available observations.
