Metal Droplet Effects on the Composition of Ternary Nitrides
Mani Azadmand, Stefano Vichi, Sergio Bietti +7
We investigate effects of metal droplets on the In incorporation in InGaN epilayers grown at low temperature (450 C) by plasma assisted molecular beam epitaxy. We find a strong red…

Droplet Controlled Growth Dynamics in Plasma-Assisted Molecular Beam Epitaxy of In(Ga)N Materials
Mani Azadmand, Luca Barabani, Sergio Bietti +7
We investigate the effect of the formation of metal droplets on the growth dynamics of InGaN by Plasma-Assisted Molecular Beam Epitaxy (PAMBE) at low temperatures (T = 450°C). We f…

Disentangling nonradiative recombination processes in Ge micro-crystals on Si substrates
F. Pezzoli, A. Giorgioni, K. Gallacher +9
We address nonradiative recombination pathways by leveraging surface passivation and dislocation management in micron-scale arrays of Ge crystals grown on deeply patterned Si subst…
