Correction of height-fluctuation-induced systematic errors in polymers by AFM-based nanomechanical measurements

Polymer Testing, 2021
AFM-based nanomechanical measurements are powerful tools for the characterization of polymer composites. However, a flat surface of the samples is usually required, which restricts the wide applications of nanomechanical measurements.

Dynamic Characteristics Design System for 3D Nanostructure Fabricated by FIB-CVD

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2010
Small-sized structures of diamond-like carbon (DLC) deposited by FIB-CVD contain microscopic non-uniformity in their mechanical properties. This is mainly due to the structures containing Ga implanted by Ga ion irradiation during deposition [1].
