A Piezoelectric Goniometer Inside a TEM Goniometer

Microscopy and Microanalysis (impact factor: 3.01). 01/2010; 2:1784. pp.1784

ABSTRACT Piezoelectric nanoactuators, which can provide extremely stable and reproducible positioning, are rapidly becoming the dominant means for position control in transmission electron microscopy (TEM). This technology links the accurate manipulation of samples at the nanometer regime with TEM's imaging resolution and therefore offers a better way to advance the understanding of the properties of nano-scale systems. A family of piezo-drives inserted into TEM goniometers have been developed for different applications, such as nano-contacting, electrical measurement, mechanical and tribological test by indentation, as well as electron tomography which reveals the objects' physical and chemical structures in three dimensions (3D).
