Jiang, J., Yuan, J. and Bleloch, A. (2007) Cluster scale composition determination in a boron-rich compound. Applied Physics Letters, 91 (11). pp. 113107-1. ISSN 0003-6951
Composition metrology is an important issue for compound nanostructure and devices. By imaging the internal structure of boron clusters in a boron-rich material using the high angle annular dark field technique in an aberration-corrected scanning transmission electron microscope, the authors have been able to determine quantitatively the local composition to be B6O1−x (x=0.30±0.04) through a relative image contrast analysis with the aid of a dynamical electron scattering simulation. Fluctuation of the oxygen occupancy is spatially resolved. This high precision and efficient measurement allows the study of the nonstoichiometry effect on an atomic scale for boron-rich materials.
