Monolithically integrated 940 nm half VCSELs on bulk Ge substrates
Yunlong Zhao, Jia Guo, Markus Feifel +7
High quality n-type AlGaAs distributed Bragg reflectors (DBRs) and lnGaAs multiple quantum wells were successfully monolithically grown on 4-inch off-cut Ge (100) wafers. The grown…
Study of monolithically integrated 940 nm AlGaAs distributed Bragg reflectors on graded GaAsP/bulk Si substrates
Jia Guo, Yunlong Zhao, Markus Feifel +7
We report the fabrication of monolithically integrated 940 nm AlGaAs distributed Bragg reflectors (DBRs) on graded GaAsP/Si substrates. Low-density surface bumps and cross-hatch pa…
Monolithic integration of 940 nm AlGaAs distributed Bragg reflectors on bulk Ge substrates
Yunlong Zhao, Jia Guo, Markus Feifel +8
High quality 940 nm AlGaAs n-type distributed Bragg reflectors (DBRs) were successfully monolithically grown on off-cut Ge (100) substrates. The Ge-DBRs have reflectivi…
Counterbalancing light absorption and ionic transport losses in the electrolyte for integrated solar water splitting with III-V/Si dual-junctions
Moritz Kölbach, Ciler Özen, Oliver Höhn +4
Recently, significant progress in the development of III-V/Si dual-junction solar cells has been achieved. This not only boosts the efficiency of Si-based photovoltaic solar cells,…
