Optically controlled dual-band quantum dot infrared photodetector
Stefano Vichi, Sergio Bietti, Francesco Basso Basset +3
We present the design for a novel type of dual-band photodetector in the thermal infrared spectral range, the Optically Controlled Dual-band quantum dot Infrared Photodetector (OCD…
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…
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…
Spectral broadening in self-assembled GaAs quantum dots with narrow size distribution
Francesco Basso Basset, Sergio Bietti, Artur Tuktamyshev +3
The control over the spectral broadening of an ensemble of emitters, mainly attributable to the size and shape dispersion and the homogenous broadening mechanisms, is crucial to se…
