Femtosecond pump-probe absorption edge spectroscopy of cubic GaN
Elias Baron, Rüdiger Goldhahn, Shirly Espinoza +6
Time-dependent femtosecond pump-probe spectroscopic ellipsometry studies on zincblende gallium-nitride (zb-GaN) are performed and analyzed between 2.9-3.7eV. An ultra-fast change o…
Extremely low energy ARPES of quantum well states in cubic-GaN/AlN and GaAs/GaAlAs heterostructures
Mahdi Hajlaoui, Stefano Ponzoni, Michael Deppe +6
Quantum well (QW) heterostructures have been extensively used for the realization of a wide range of optical and electronic devices. Exploiting their potential for further improvem…
Lasing of donor-bound excitons in ZnSe microdisks
A. Pawlis, M. Panfilova, D. J. As +4
Excitons bound to flourine atoms in ZnSe have the potential for several quantum optical applications. Examples include optically accessible quantum memories for quantum information…
MBE growth of cubic AlxIn1-xN and AlxGayIn1-x-yN lattice matched to GaN
D. J. As, M. Schnietz, J. Schoermann +4
Ternary and quaternary cubic c-AlxIn1-xN/GaN and c-AlxGayIn1-x-y/GaN heterostructures lattice-matched to c-GaN on freestanding 3C-SiC substrates were grown by plasma-assisted molec…
MBE Growth of Cubic InN
J. Schoermann, D. J. As, K. Lischka
Cubic InN films were grown on top of a c-GaN buffer layer by rf-plasma assisted MBE at different growth temperatures. X-Ray diffraction investigations show that the c-InN layers co…
Room temperature green light emissions from nonpolar cubic InGaN/GaN multi quantum wells
S. F. Li, J. Schoermann, D. J. As +1
Cubic InGaN/GaN multi quantum wells (MQWs) with high structural and optical quality are achieved by utilizing free-standing 3C-SiC (001) substrates and optimizing InGaN quantum wel…
