Twinning in AuCu3(Ag) II long-period superlattice
نویسنده
چکیده
Ternary Au-Ag-Cu alloys differing in composition were produced by means of a sequential gradual sputtering of elemental thin films. The resultant multilayers were then subjected to various heat treatments to promote a phase formation by interdiffusion. A long-period superlattice AuCu3 I1 was found among the different phases. The microstructure of this phase revealed growth stacking faults and twins. The defect formation is explained by a semi-quantitative model based on the electron theory of metals. Some applications of this model concerning the domain size of long-period superlattices are also discussed. 0

Coherent twinning phenomena: towards twinning superlattices in III-V semiconducting nanowires.
We report evidence in GaP and InP nanowires for a coherent modulation of the structure along the wire axis. By using electron diffraction, we have observed an additional series of diffraction peaks consistent with a quasiperiodic placement of twinning boundaries along the wire. This observation is indeed unexpected, as the vapor-liquid-solid growth conditions used to produce the nanowires were ...
متن کاملGrowth and properties of coherent twinning superlattice nanowires.
Although coherent twin boundaries require little energy to form in nanoscale single crystals, their influence on properties can be dramatic. In recent years, some important steps forward have been made in understanding and controlling twinning processes at the nanoscale, making possible the fabrication of nanoengineered twinning superlattices in crystalline nanowires. These advances have opened...
متن کاملOscillatory behavior in the electrical resistivity of transition-metal superlattices
The electrical resistivity of Co/Ni and Cu/Ni superlattices exhibit resistivity oscillations as a function of superlattice period L, while Ag/Pd does not. Moreover, the resistivity of Co/Ni superlattices shows quantum size effects and a resistivity enhancement with L, as a function of total film thickness d . These results are consistent with a model which assumes d-electron localization in the...
متن کاملUmklapp process in observation of coherent folded longitudinal acoustic phonons in a GaAs/AlAs long-period superlattice
Coherent folded longitudinal acoustic phonons in a GaAs/AlAs long-period superlattice have been investigated by using a reflection-type two-color pump-probe technique under the condition that the wave vector of the probe pulse in the sample exceeds the mini-Brillouin zone. The coherent oscillations observed in the time-domain signals indicate the propagation of the phonon wave packet through th...
متن کاملA general method to determine twinning elements
The fundamental theory of crystal twinning has been long established, leading to a significant advance in understanding the nature of this physical phenomenon. However, there remains a substantial gap between the elaborate theory and the practical determination of twinning elements. This paper proposes a direct and simple method - valid for any crystal structure and based on the minimum shear c...
