Highlights
•The thickness of graphene grown on SiC was determined by AES depth profiling.
•The AES depth profiling verified the presence of buffer layer on SiC.
•The presence of unsaturated Si bonds in the buffer layer has been shown.
•Using multipoint analysis thickness distribution of the graphene on [...]
InGaAs HEMTs form two-stage gain blocks delivering 9 dB of gain while consuming just 20 mW
A TEAM of Taiwanese engineers has used flip-chip packaging to build anInGaAs HEMT delivering up to 6.5 dB of gain at 60 GHz.
The researchers argue that one of the [...]

This paper reports the mechanical and electrical characteristics of Ge/Ge interfaces prepared by room-temperature surface-activated bonding (SAB). Bonded Ge/Ge wafer pairs with high bonding strength equivalent to that of the bulk material were achieved without any heat treatment. It was found that the bonding [...]

Towards the cost effective epitaxy of hillocks free CdZnTe film on (001)GaAs by close-spaced sublimation
Cost-effective epitaxy of hillocks free CdZnTe films on (001)GaAs was explored with close-spaced sublimation (CSS) technique. The orientation and film quality were studied with scanning electron microscopy (SEM), X-ray diffraction θ–2θ and Φ scans [...]
