Abstract

An in-situ nanoscale observational and force measurement setup is a significant tool that is necessary for understanding the fundamental properties of materials. We have integrated two actuators and two beams into MEMS device, and then developed an experimental setup which enabled us to tilt the device around two axes and detect applied forces in two directions. To demonstrate the tilting capability, silicon tips made from a (100) wafer were prepared and the diffraction patterns of the specimen were observed, indicating that the observation direction was aligned on the [100] zone axis. Furthermore we successfully observed the peeling of a nano-junction at the nano-scale while simultaneously detecting the x and y components of the applied forces in real-time.

Impact Statement

A custom-made MEMS device was fabricated to add mechanical capabiliaites by which one can investigate nanomechanical properties of different materiasl and structures
