We elucidate the evolution of the entrained air in drop impact on a wide range of liquids, using ultrafast X-ray phase-contrast imaging. We elaborate the retraction mechanism of the entrapped air film in terms of liquid viscosity. We found the criter

2020 IEEE Symposium on VLSI Technology.
We have demonstrated a complete set of on-chip Si-photonic components using our III/V-on-bulk-silicon (Si) technology. Our bulk-Si-based technology shows unrivaled CMOS compatibility and much improved thermal dissipation, leading to superior performa
