مشخصه‌یابی ‌ساختارهای دورآلائیده وارون p-Si/SiGe/Si با روشهای پرتو X و الکتریکی

In this work, the epitaxially grown, lattice–matched p-Si/Si1-xGex/Si inverted remote doped structures have been characterized using X-ray and electrical techniques. The Si cup layer thickness () and Ge content (x) have been determined from computer simulation of intensity and angular sepration of (004) peaks observed in the X-ray diffraction pattern due to misorientaion of corresponding Bragg ...

Model and Methods Energy Hamiltonian.To extend a structure-based model to systems with multiple basins, we modified the contact map and the dihedral angles. Note that all the residue indexes are rearranged from 1 to 366 in the model. To include the side chain dynamics on the conformational change of enzyme, we developed a coarse-grained model in which each amino acid is represented by one or tw...

Characterization of Si/Si 1 -,Ge,/Si quantum wells by cathodoluminescence imaging and spectroscopy

Cathodoluminescence (CL) imaging and spectroscopy have been used to characterize fully strained SiGe quantum wells grown on Si. At T-5 K, the CL spectra contain only band edge luminescence features. Monochromatic imaging with the no-phonon line attributed to the bound excitons in the quantum well, has shown that the distribution of the luminescence from the wells is not uniform. The thinnest we...

Revealing heterogeneous nucleation of primary Si and eutectic Si by AlP in hypereutectic Al-Si alloys.

The heterogeneous nucleation of primary Si and eutectic Si can be attributed to the presence of AlP. Although P, in the form of AlP particles, is usually observed in the centre of primary Si, there is still a lack of detailed investigations on the distribution of P within primary Si and eutectic Si in hypereutectic Al-Si alloys at the atomic scale. Here, we report an atomic-scale experimental i...
