Semiconductor quantum dots (QDs) are nanostructures that can enhance the performance of electronic devices due to their 3D quantization. Typically, heterovalent impurities, or dopants, added semiconducting QDs provide extra electrons and improve conductivity. Since each QD is expected contain a few parent dopants have been difficult locate. In this work, we investigate spatial distribution donors in epitaxial InAs/GaAs using local-electrode atom-probe tomography self-consistent...
We present a phase-field dislocation dynamics (PFDD) model informed by first-principle calculations to elucidate the competitive nucleation and propagation between glide shuffle sets in InSb diamond cubic crystal. The are directly with generalized stacking fault energy curves on (111) slip plane for both “glide set,” smaller interplanar spacing, “shuffle larger spacing. formulation also includes elastic anisotropy gradient term associated core. PFDD show that under no stress equilibrium...
