Eutectic growth in space

Lamellar eutectic growth with anisotropic interphase boundaries

We present a numerical study of the effect of a free-energy anisotropy of the solidsolid interphase boundaries on the formation of tilted lamellar microstructures during directional solidification of nonfaceted binary eutectic alloys. We used two different methods – phase-field (PF) and dynamic boundary-integral (BI) – to simulate the growth of periodic eutectic patterns in two dimensions. For ...

The mechanism of eutectic growth in highly anisotropic materials

In the past 50 years, there has been increasing interest-both theoretically and experimentally-in the problem of pattern formation of a moving boundary, such as a solidification front. One example of pattern formation is that of irregular eutectic solidification, in which the solid-liquid interface is non-isothermal and the interphase spacing varies in ways that are poorly understood. Here, we ...

Controlled Growth of Rubrene Nanowires by Eutectic Melt Crystallization

Organic semiconductors including rubrene, Alq3, copper phthalocyanine and pentacene are crystallized by the eutectic melt crystallization. Those organic semiconductors form good eutectic systems with the various volatile crystallizable additives such as benzoic acid, salicylic acid, naphthalene and 1,3,5-trichlorobenzene. Due to the formation of the eutectic system, organic semiconductors havin...
