Droplet Epitaxy and applications
2014The semiconductor quantum dot (QD) intermediate band solar cells (IBSC) design introduce an extension of the absorption coefficient of the host semiconductor to lower energies without voltage loss [1]. The IBSC working mechanisms have been demonstrated via Stranski-Krastavov self-assembly of InAs QDs in GaAs, but many issues such as strain defect ...

GaAs based nanostructures grown by droplet epitaxy
2011What makes three dimensional semiconductor quantum nanostructures (QN) so attractive is the possibility to tune their electronic properties by careful design of their size and composition. These parameters set the confinement potential of electrons and holes, thus determining the electronic and optical properties of the QN.

Droplet epitaxy nanostructures for device applications
2014Droplet epitaxy (DE) is a non-conventional growth technique based on molecular beam epitaxy. This method allows for the fabrication of lattice-matched and strain-free self-assembled III-V nanostructures, reducing the size dispersion between 5 and 20%.

Control of GaAs nanostructures shape in droplet epitaxy
2011Physical properties of nanostructures are strongly influenced by their dimensions and shapes, so that only a precise control on the nanocrystals morphology can allow for the fine tuning of their electronic properties. The droplet epitaxy (DE) [1] is a flexible growth method, based on the molecular beam epitaxy, which allows for the fabrication of a ...
