Telecom-wavelength InAs QDs with low fine structure splitting grown by droplet epitaxy on GaAs(111)A vicinal substrates
A. Tuktamyshev, A. Fedorov, S. Bietti +8
We present self-assembly of InAs/InAlAs quantum dots by droplet epitaxy technique on vicinal GaAs(111)A substrates. The small miscut angle, while maintaining the symmetries imposed…
Reentrant behavior of the density vs temperature of indium islands on GaAs(111)A
Artur Tuktamyshev, Alexey Fedorov, Sergio Bietti +4
We show that the density of indium islands on GaAs(111)A substrates have a non-monotonic, reentrant behavior as a function of the indium deposition temperature. The expected increa…
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…
Spatial Point Analysis of Quantum Dot Nucleation Sites on InAs Wetting Layer
Tomoya Konishi, Shiro Tsukamoto
We perform spatial point analysis of InAs quantum dot nucleation sites and surface reconstruction domain pattern on an InAs wetting layer, giving insights for quantum dot nucleatio…
Structure analysis of the Ga-stabilized GaAs(001)-c(8x2) surface at high temperatures
Akihiro Ohtake, Shiro Tsukamoto, Markus Pristovsek +2
Structure of the Ga-stabilized GaAs(001)-c(8x2) surface has been studied using rocking-curve analysis of reflection high-energy electron diffraction (RHEED). The c(8x2) structure e…
