Peeling by Pulling: Characterizing the Mechanical Behavior of Nanoscale Thin Films
نویسندگان
چکیده
The flexible and clinging nature of ultra-thin films require the understanding their elastic adhesive properties in a wide range circumstances from fabrications to applications. Simultaneously measuring both properties, however, is extremely difficult as film thickness diminishes nanoscales. In this talk, I will show our recent work that addresses such difficulties through peeling by vertically pulling thin off substrates (we thus refer it “pull-to-peel”). Particularly, we perform in-situ pull-to-peel graphene MoS2 scanning electron microscope achieve simultaneous determination Young’s moduli adhesions gold substrates. This striking contrast other conceptually similar tests available literature, including indentation (only elasticity) spontaneous blisters adhesion). Furthermore, weakly nonlinear Hooke’s relation for response two-dimensional materials, which may be harnessed design nanoscale force sensors or exploited thin-film systems.

In this study, NiTi thin films were deposited on the glass and NaCl substrates by means of magnetron sputtering method. The influence of aging temperature, over the range 300-500 oC, on phase transformation and mechanical properties of the sputtered NiTi thin films were studied by differential scanning calorimetry (DSC) and nano-indentation assay, respectively. The DSC curves showed that the ag...
متن کاملFullerenes as adhesive layers for mechanical peeling of metallic, molecular and polymer thin films
We show that thin films of C60 with a thickness ranging from 10 to 100 nm can promote adhesion between a Au thin film deposited on mica and a solution-deposited layer of the elastomer polymethyldisolaxane (PDMS). This molecular adhesion facilitates the removal of the gold film from the mica support by peeling and provides a new approach to template stripping which avoids the use of conventional...
متن کاملMechanical Properties and Microstructural Evolution of Ta/TaNx Double Layer Thin Films Deposited by Magnetron Sputtering
Crystalline tantalum thin films of about 500nm thickness were deposited on AISI 316L stainless steel substrate using magnetron sputtering. To investigate the nano-mechanical properties of tantalum films, deposition was performed at two temperatures (25°C and 200°C) on TaNx intermediate layer with different N2/Ar flow rate ratio from 0 to 30%. Nano-indentation was performed to obtain the mechani...
