Atom Probe is 50 Years Old

50 Years Old and Still Alive: Eigenproblems

2004 survey of physicians 50 to 65 years old.

Cold-atom scanning probe microscopy.

Scanning probe microscopes are widely used to study surfaces with atomic resolution in many areas of nanoscience. Ultracold atomic gases trapped in electromagnetic potentials can be used to study electromagnetic interactions between the atoms and nearby surfaces in chip-based systems. Here we demonstrate a new type of scanning probe microscope that combines these two areas of research by using ...

Atom-probe Analysis of Zircaloy

Zirconium based alloys in the Zircaloy series have been analysed with atom-probe field-ion microscopy. During specimen preparation an anodic layer is formed, containing about 50% oxygen. In preliminary analyses of the matrix al1 the minor elements Fe, Ni, Cr and O were detected, and it appears possible to determine with the atom-probe whether any particular heat treatment causes matrix depletio...

Atom probe tomography in nanoelectronics

The role of laser assisted atom probe tomography (APT) in microelectronics is discussed on the basis of various illustrations related to SiGe epitaxial layers, bipolar transistors or MOS nano-devices including gate all around (GAA) devices that were carried out at the Groupe de Physique des Matériaux of Rouen (France). 3D maps as provided by APT reveal the atomic-scale distribution of dopants a...
