Velocity selection problem in the presence of the triple junction.
نویسندگان
چکیده
Melting of a bicrystal along the grain boundary is discussed. A triple junction plays a crucial role in the velocity selection problem in this case. In some range of the parameters an entirely analytical solution of this problem is given. This allows us to present a transparent picture of the structure of the selection theory. We also discuss the selection problem in the case of the growth of a "eutectoid dendrite."

In this paper, the purpose is to improve the efficiency of triple-junction solar cell by introducing quantum well into GaAs junction. Firstly, InGaP/GaAs/InGaAs triple-junctions solar cell has been simulated. Then, a multiple stepped quantum wells (MSQWs), in which InGaAs well is sandwiched by InGaAsP as stepped layer, and the barrier is GaAs, has been introduced into intrinsic region of single...

متن کاملTriple Junction Mobility: A Molecular Dynamics Study
We present a molecular dynamics simulation study of the migration of individual grain boundary triple junctions. The simulation cell was designed to achieve steady state migration. Observations of the triple junction angle and grain boundary profiles confirm that steady state was achieved. The static, equilibrium grain boundary triple junction angles and the dynamic triple junction angles were ...
