Stability of the chevron domain at triple-line reconstructions
(American Physical Society, 2004)
The line of emergence of a grain boundary at the surface of a face centered cubic crystal may decompose into a nanoscale triangular prism with a chevronlike structure. This behavior has been found in gold, and we address ...
Raman scattering and infrared absorption in multiple boron-doped Ge dots
(American Institute of Physics Inc.American Vacuum Society, 1999)
Multiple boron-doped Ge quantum dots are investigated. The structure, which consists of 20 periods of Ge quantum dots stacked with 6 nm Si spacers, is grown on a Si (100) substrate by solid source molecular beam epitaxy. ...
Chevron defect at the intersection of grain boundaries with free surfaces in Au
(American Physical Society, 2002)
We have identified a new defect at the intersection between grain boundaries and surfaces in Au using
atomic resolution transmission electron microscopy. At the junction line of 90
h110i tilt grain boundaries
of ...
Raman scattering from a self-organized Ge dot superlattice
(American Institute of Physics Inc., 1999)
We present a Raman scattering study of a self-organized Ge dot superlattice. The structure, which consists of 20 periods of Ge quantum dots sandwiched by 6 nm Si spacers, is grown on a Si (100) substrate by solid source ...
Determination and distribution of heavy metals in crops harvested in 2001 from different parts of Serbia
(Scientific Bulgarian Communication, 2004)
One-dimensional random walk of nanosized liquid Pb inclusions on dislocations in Al
(Taylor & Francis, 2004)
Migration of nanosized liquid Pb inclusions attached to dislocations in Al
has been observed during in-situ transmission electron microscopy heating
experiments and monitored by real-time video recordings. The movements ...
Synthesis and structure of colloidal bimetallic nanocrystals: the non-alloying system Ag/Co
(American Chemical Society, 2002)
Monodisperse bimetallic Ag/Co composite nanocrystals have been prepared using colloid chemistry methods. Transmission electron microscopy showed well isolated Ag/Co particles centered around 12 nm in diameter. The composition ...
Population doses from terrestrial gamma exposure in Serbia
(Institute of Oncology, 2007)
Background: Terrestrial radiation emitted from naturally occurring radionuclides, such as 40K and radionuclides from the 238U
and 232Th series and their decay products represent the main external source of irradiation to ...
Random vibration movements of liquid nanosized Pb inclusions in Al
(Elsevier B.V., 2004)
Transmission electron microscopy has been used to study the behavior of liquid nanosized Pb inclusions in Al ribbons made by rapid solidification. In situ heating experiments carried out in the temperature range from around ...
Growth study of surfactant-mediated relaxed SiGe graded layers for 1.55-μm photodetector applications
(Elsevier Sequoia SA, 2000)
A systematic study of Sb sufactant-mediated relaxed SiGe graded layers has been performed. The results have been compared
with those of relaxed SiGe layers grown at high temperatures, showing that the Sb-mediated SiGe ...
