Self‐Assembled Telecom Color Centers in Silicon and Their Growth Environment

Advanced Physics Research, EarlyView.
Influence of the growth pressure during the formation of self‐assembled color centers in silicon grown by molecular beam epitaxy at ultra‐low temperatures on the color center's photoluminescence spectral signature. The growth pressure crucially determines color center selectivity, as evidenced by G‐centers, W‐centers, and T‐centers, matrix purity, and ...

Revisiting Dopant Deactivation In Silicon Nanostructures

Advanced Physics Research, EarlyView.
Dopant activation is essential for the operation of semiconductor devices. On the nanoscale, however, quantum confinement and dielectric mismatch impede dopant activation. Here, we study the ionization of phosphorous in ultrathin silicon films embedded in different dielectric environments.

On the Impact of Mechanical Constraint on Band Structure and Photo‐Elastic Effect in Photonic Resonators

Advanced Physics Research, EarlyView.
We computationally investigate the mechanical, electronic, and optical properties of strained GeSn microdisks on silicon substrates. By combining photo‐elasticity, strain‐dependent band‐structure calculations, and optical mode analysis, we study how strain distribution, structural configuration, and temperature affect the electronic band structure and ...

Diffusion‐Governed Growth Mechanisms of Epitaxial GaAs Islands on CMOS‐Compatible Si(001) Nanotip Arrays

Advanced Physics Research, EarlyView.
The mechanism and kinetics of selective GaAs growth on Si nanotip wafers via nanoheteroepitaxy were investigated as a function of pitch (center‐to‐center nanotip spacing). The pitch dependence reveals distinct surface‐diffusion‐controlled regimes, demonstrating that lateral Ga adatom transport on the SiO2 mask governs material redistribution and ...
