Toward thin GaSb Buffer Layers Grown on On‐Axis (001) Silicon by Molecular Beam Epitaxy
Published 2025-01-01“…Abstract The monolithic integration of III‐Vs on Silicon (Si) is of great interest for the development of active photonic integrated circuits (PICs). The main challenge is to achieve a high‐quality epitaxy of the III‐V on the Si substrate, as the differences between the materials are responsible for the formation of crystal defects, in particular threading dislocations (TDs) and antiphase domains (APDs) delineated by antiphase boundaries (APBs), which degrade the device's performance. …”

Facile Conversion and Optimization of Structured Illumination Image Reconstruction Code into the GPU Environment
Published 2024-01-01“…Superresolution, structured illumination microscopy (SIM) is an ideal modality for imaging live cells due to its relatively high speed and low photon-induced damage to the cells. The rate-limiting step in observing a superresolution image in SIM is often the reconstruction speed of the algorithm used to form a single image from as many as nine raw images. …”
