SiGe HBT wideband amplifier for millimeter wave applications

open access: yesJournal of Telecommunications and Information Technology, 2023
A wideband amplifier up to 50 GHz has been implemented in a 0.25 μm, 200 GHz ft SiGe BiCMOS technology. Die size was 0.7×0.73 mm2. The two-stage design achieves more than 11 dB gain over the whole 20 to 50 GHz band. Gain maximum was 14.2 dB at 47.5 GHz.

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

open access: yesAdvanced 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 ...

Strain‐Tunable Photoluminescence From Ge Quantum Dots on Si Nanotips for CMOS‐Compatible Photonics

open access: yesAdvanced Physics Research, EarlyView.
This work studies strain in Ge quantum dots grown on Si nanotips using photoluminescence, X‐ray diffraction, and band structure calculations. It shows how emission changes with dot size, evaluates strain in the dot and substrate, and explains the role of direct and indirect transitions in the optical behavior.
