Size-dependent shape characteristics of 2D crystal blisters

Submitted by Yifan Rao on

Dear friends, I want to share our recent work on the shape characteristics of 2D crystal blisters. Micro- and nano-sized blisters can form spontaneously when two-dimensional (2D) crystals are transferred onto substrates because liquid molecules that are initially adsorbed on 2D material and substrate surfaces can be squeezed and trapped by interfacial forces. On the one hand, blisters are undesirable in 2D material devices as they impede charge/photon/phonon transport across the interface, so various means were developed to eliminate interfacial blisters. On the other hand, m

Linear perturbation analysis in ABAQUS with surface to surface contact

Hi, I tried a Linear perturbation analysis in ABAQUS with surface-to-surface contact. The parts that are defined as contacting surfaces are 0.2mm apart. They are also given a normal behavior with a pressure overclosure option using "hard" contact. However, in some modes where it is expected to be in contact, there is interpenetration. The problem is that it depends on the scale of deformation too. So my question is how to make this generalised, i.e., include no contact in case of tensile mode behaviour and include high stiffness in case of mode involving compressive type behaviour?
