Glass transitions of freely suspended polymer films
We present a modified version of our " sliding model " , where chain arcs, between two contacts at the surface, may move if all the barriers along the arc are weaker than a certain threshold. An important advance of the revised model is that the high limiting chain lengths N * observed in the experiments (N * ∼ 10 4) are naturally accounted for. In this model, a film of thickness h < 2R 0 (wher...
متن کاملEvaporation of freely suspended single droplets
Evaporation is ubiquitous in nature. This process influences the climate, the formation of clouds, transpiration in plants, the survival of arctic organisms, the efficiency of car engines, the structure of dried materials and many other phenomena. Recent experiments discovered two novel mechanisms accompanying evaporation: temperature discontinuity at the liquid–vapour interface during evaporat...
متن کاملFreely suspended two - dimensional electron gases
We present a new technique allowing us to build freely suspended two-dimensional electron gases from AlGaAs/GaAs/AlAs heterostructures. This technique relies on an MBE-grown structures that includes a sacrificial layer. ( 1998 Elsevier Science B.V. All rights reserved.
متن کاملOptical Properties of DeVries Liquid Crystals and a Look at Ultra Thin Freely Suspended Smectic Films
Liquid crystals exist as a fourth state of matter. They are anisotropic and due to this order, they affect light that passes through them, making them ideal candidates for optical study. By employing a basic technique for measuring a liquid crystal’s birefringence and tilt angle, one is able to study a number of other properties such as the electroclinic effect. In addition, smectic liquid crys...
متن کاملMechanical properties of freely suspended semiconducting graphene-like layers based on MoS2
We fabricate freely suspended nanosheets of molybdenum disulphide (MoS2) which are characterized by quantitative optical microscopy and high-resolution friction force microscopy. We study the elastic deformation of freely suspended nanosheets of MoS2 using an atomic force microscope. The Young's modulus and the initial pre-tension of the nanosheets are determined by performing a nanoscopic vers...
