Highlights
•A recessed structure was used on the GaAs/Si solar cells to reduce the current path.
•The associated series resistance was reduced by a recessed structure.
•The carrier recombination loss was improved due to pyramid-like recessed structure.
In this study, epitaxial layers of GaAs-based solar cells were grown [...]

Extended defects and precipitates in LT-GaAs, LT-InAlAs and LT-InP
We review the main structural characteristics of low temperature molecular beam epitaxially produced GaAs (LT-GaAs), LT-InAlAs, and LT-InP. These materials exhibit almost identical behaviours with respect to growth and annealing conditions. For too low growth temperatures [...]
In this study, a nano-columnar low-temperature (LT) GaN buffer was used to reduce the wafer bowing of a GaN layer grown on a sapphire substrate. A significant reduction in the extent of wafer bowing was observed for the GaN layer for the preserved nano-columnar LT GaN [...]
Gartner: worldwide semiconductor revenue declined 2.3% in 2015
Worldwide semiconductor revenue totaled 334.8 billion dollar in 2015, a 2.3 percent decline from 2014, according to final results by Gartner. The combined revenue of the top 25 semiconductor vendors fell by 0.5 percent during 2015. This was [...]
