Vapor-phase growth of amorphous materials: A molecular-dynamics study.

Crystallization Kinetics Study in Al87Ni10La3 Amorphous Alloy

In this study, the crystallization behavior of melt-spun Al87Ni10La3 amorphous phase was investigated by using X-ray diffraction and non-isothermal differential thermal analysis techniques. The results demonstrated that the amorphous phase exhibited two-stage crystallization on heating, i.e., at first step the amorphous phase transforms into α-Al phase and at second step Al11La3 and Al3Ni inter...

Organic Vapor Phase Deposition for Optoelectronic Devices

The growth of molecular organic thin films by the process of organic vapor phase deposition (OVPD) was initiated by Professor Steve Forrest OVPD transports organic molecules to a cold substrate by a hot inert carrier gas. It has proven useful for the deposition of organic semiconductors, and is capable of patterned growth with micron resolution. Professors Benziger and Forrest collaborated to e...

Maxwell rigidity and topological constraints in amorphous phase-change networks

By analyzing first-principles molecular-dynamics simulations of different telluride amorphous networks, we develop a method for the enumeration of radial and angular topological constraints, and show that the phase diagram of the most popular system Ge-Sb-Te can be split into two compositional elastic phases: a tellurium rich flexible phase and a stressed rigid phase that contains most of the m...

Molecular deformation mechanisms and mechanical properties of polymers simulated by molecular dynamics

Virtual polymeric materials were created and used in computer simulations to study their behavior under uniaxial loads. Both single-phase materials of amorphous chains and two-phase polymer liquid crystals (PLCs) have been simulated using the molecular dynamics method. This analysis enables a better understanding of the molecular deformation mechanisms in these materials. It was confirmed that ...
