摘要
Crowd-surfing quantum dots: Quantum-dot Langmuir layers (see picture) were compressed beyond their collapse pressure, resulting in phase transitions where particles are promoted from a monolayer into a bi- or even a trilayer depending on the applied pressure. The procedure works for different quantum dot types and can be rationalized from thermodynamic considerations. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
