Effect of modulation-doping on luminescence properties of plasma assisted MBE-grown GaN/AIGaN quantum well

Kamata, N.; Klausing, H.; Fedler, F.; Mistele, D.; Aderhold, J.; Semchinova, O.K.; Graul, J.; Someya, T.; Arakawa, Y. (Cambridge : Cambridge University Press, 2004)

In order to improve the crystal quality of GaN-based light emitting devices, photoluminescence (PL) characterization of below-gap states in plasma assisted MBE-grown GaN/AlGaN quantum well (QW) structures has been done by ...
Experimental setup for camera-based measurements of electrically and optically stimulated luminescence of silicon solar cells and wafers

Hinken, David; Schinke, Carsten; Herlufsen, Sandra; Schmidt, Arne; Bothe, Karsten; Brendel, Rolf (College Park, MD : American Institute of Physics, 2011)

We report in detail on the luminescence imaging setup developed within the last years in our laboratory. In this setup, the luminescence emission of silicon solar cells or silicon wafers is analyzed quantitatively. Charge ...
Luminescence emission from forward- and reverse-biased multicrystalline silicon solar cells

Bothe, Karsten; Ramspeck, K.; Hinken, D.; Schinke, Carsten; Schmidt, J.; Herlufsen, S.; Brendel, Rolf; Bauer, J.; Wagner, J.-M.; Zakharov, N.; Breitenstein, O. (College Park, MD : American Institute of Physics, 2009)

We study the emission of light from industrial multicrystalline silicon solar cells under forward and reverse biases. Camera-based luminescence imaging techniques and dark lock-in thermography are used to gain information ...
New age constraints for the Saalian glaciation in northern central Europe: Implications for the extent of ice sheets and related proglacial lake systems

Lang, Jörg; Lauer, Tobias; Winsemann, Jutta (Amsterdam : Elsevier, 2018)

A comprehensive palaeogeographic reconstruction of ice sheets and related proglacial lake systems for the older Saalian glaciation in northern central Europe is presented, which is based on the integration of palaeo-ice ...
Temperature-dependent luminescence spectroscopic and mass spectrometric investigations of U(VI) complexation with aqueous silicates in the acidic pH-range

Lösch, Henry; Raiwa, Manuel; Jordan, Norbert; Steppert, Michael; Steudtner, Robin; Stumpf, Thorsten; Huittinen, Nina (Amsterdam [u.a.] : Elsevier Science, 2020)

In this study the complexation of U(VI) with orthosilicic acid (H4SiO4) was investigated between pH 3.5 and 5 by combining electrospray ionization mass spectrometry (ESI-MS) and laser-induced luminescence spectroscopy. The ...
Towards bose-einstein condensation of semiconductor excitons: The biexciton polarization effect

Hägele, D.; Pfalz, S.; Oestreich, Michael (College Park, MD : American Physical Society, 2009)

We theoretically predict a strong influence of stimulated exciton-exciton scattering on semiconductor luminescence. The stimulated scattering causes circularly polarized instead of unpolarized emission at the biexciton ...
