Hydrodynamics and microphase ordering in block copolymers: Are hydrodynamics required for ordered phases with periodicity in more than one dimension?
(The American Institute of Physics, 2004-12-08)
We use Brownian dynamics (BD), molecular dynamics, and dissipative particle dynamics to study the phase behavior of diblock copolymer melts and to determine if hydrodynamics is required in the formation of phases with ...
Temperature dependence of deformation-assisted crystallization in amorphous Fe78B13Si9Fe78B13Si9
(The American Institute of Physics, 1998-09-28)
Low-energy ball milling of amorphous Fe78B13Si9Fe78B13Si9 has been performed at temperatures between 25 and 250 °C. Primary crystallization is observed after milling at elevated temperatures, but not after annealing at the ...
Characteristics of dislocations at strained heteroepitaxial InGaAs/GaAs interfaces
(The American Institute of Physics, 1989-10-01)
The formation, interaction, and propagation of misfit dislocations in molecular‐beam epitaxial InGaAs/GaAs heterointerfaces have been studied by transmission electron microscopy. With the lattice mismatch less than 2%, ...
Molecular dynamics study of cristobalite silica using a charge transfer three-body potential: Phase transformation and structural disorder
(The American Institute of Physics, 2003-01-15)
Structural and dynamic properties of cristobalite silica have been studied using molecular dynamics simulations based on a charge transfer three-body potential model. In this potential model, the directional covalent bonding ...
Probing diffusion barrier integrity on porous silica low-k thin films using positron annihilation lifetime spectroscopy
(The American Institute of Physics, 2001-05-01)
The technique of positron annihilation lifetime spectroscopy (PALS) has been used to investigate the continuity and thermal stability of thin barrier layers designed to prevent Cu atom diffusion into porous silica, ...
Epitaxial growth and properties of metastable BiMnO3BiMnO3 thin films
(The American Institute of Physics, 2004-01-05)
Epitaxial thin films of BiMnO3BiMnO3 were deposited on single-crystal substrates of (100)-oriented SrTiO3SrTiO3 by pulsed-laser deposition. Structural analysis by x-ray diffraction, electron diffraction, and transmission ...

Experimental determination of transformation enthalpies of metastable phase transitions in ion-irradiated NiAl3
(Elsevier, 1991-07-01)
A novel experimental technique has been developed by which metastable phase transformations in thin films may be investigated. The technique is demonstrated by the determination of the enthalpies of transformation of two ...
Cooperative nucleation leading to ripple formation in InGaAs/GaAs films
(The American Institute of Physics, 2000-04-24)
In0.25Ga0.75AsIn0.25Ga0.75As epilayers were grown on GaAs (001) substrates (1.8% misfit strain) by molecular beam epitaxy to investigate the two-dimensional to three-dimensional transition as a function of thickness (t ⩽ ...
Pattern formation in a polymer thin film induced by an in-plane electric field
(The American Institute of Physics, 2004-08-16)
This letter reports experimental work involving use of an in-plane electric field to induce morphological patterns in a thin polymer film. The film was first spin coated onto a glass wafer. Then, it was heated to above its ...
