Crystal orientation measurements using transmission and backscattering

Towards 3D crystal orientation reconstruction using automated crystal orientation mapping transmission electron microscopy (ACOM-TEM)

To relate the internal structure of a volume (crystallite and phase boundaries) to properties (electrical, magnetic, mechanical, thermal), a full 3D reconstruction in combination with in situ testing is desirable. In situ testing allows the crystallographic changes in a material to be followed by tracking and comparing the individual crystals and phases. Standard transmission electron microscop...

Position and Orientation Measurements using Magnetoquasistatic Fields

The wireless position tracking problem is of increasing relevance to the society today, owing to applications such as navigation, security, and asset tracking. Despite numerous technological advances, radio based position location systems such as global positioning systems (GPS), ultrawide band (UWB) systems, and radio frequency identification (RFID) systems suffer reduced performance in non-li...

Experimental observation of the strong influence of crystal orientation on Electron Rutherford Backscattering Spectra

CORRELATION BETWEEN CRYSTAL ORIENTATION AND NANOGAP FORMED BY ELECTRO MIGRATION

Effect of electro migration on crystal structures of platinum nanowire (Nano bridge) during Nano-gap formation is investigated by means of Transmission Electron Microscopy (TEM). Selected area diffraction patterns as well as bright field images are used for this investigation. There were severely recessions in the polycrystalline Nano bridge and crystal structures around the nanogap changed ...

Laser transmission-backscattering through inhomogeneous cirrus clouds.

We have developed a two-dimensional (2D) model for inhomogeneous cirrus clouds in plane-parallel and spherical geometries for the analysis of the transmission and backscattering of high-energy laser beams. The 2D extinction-coefficient and mean effective ice-crystal size fields for cirrus clouds can be determined from a combination of the remote sensing of cirrus clouds by use of the Advanced V...
