Exciton footprint of self-assembled AlGaAs quantum dots in core-shell nanowires
Anna Fontcuberta i Morral, Martin Heiss, Eleonora Russo, Pierre Michel Corfdir, Yannik Fontana, Samuel Sonderegger
Quantum-dot-in-nanowire systems constitute building blocks for advanced photonics and sensing applications. The electronic symmetry of the emitters impacts their function capabilities. Here we study the fine structure of gallium-rich quantum dots nested in ...
American Physical Society2014Low-Pressure Chemical Vapor Deposited Zinc Oxide Films
Polycrystalline zinc oxide (ZnO) films, prepared by low-pressure chemical vapor deposition are investigated in this thesis. ZnO belongs to the class of transparent conductive oxide materials, as it is transparent to light from the visible to the near-infra ...
EPFL2013Coupling light into thin silicon layers for high-efficiency solar cells
Thin-film solar cells based on amorphous and microcrystalline silicon require thin photoactive layers to ensure a satisfactory collection of the photogenerated carriers. The small thickness is advantageous in terms of raw material consumption and industria ...
EPFL2013Dilute-Nitride Low-Dimensional Nanostructures Formed on Non-Planar Substrates
The properties of semiconductors heterostructures of nanoscopic dimensions change from that of bulk material according to the rules of quantum mechanics. The planar quantum wells (QWs) are widely used in various diode and laser devices thanks to the relati ...
EPFL2013Self-assembled quantum dots in a nanowire system for quantum photonics
Nicola Marzari, Marco Cantoni, Martin Heiss, Eleonora Russo, Sonia Conesa Boj, Yannik Fontana, Bernt Ketterer
Quantum dots embedded within nanowires represent one of the most promising technologies for applications in quantum photonics. Whereas the top-down fabrication of such structures remains a technological challenge, their bottom-up fabrication through self-a ...
Nature Publishing Group2013Stencil-Nanopatterned Back Reflectors for Thin-Film Amorphous Silicon n-i-p Solar Cells
Jürgen Brugger, Christophe Ballif, Franz-Josef Haug, Andreea Veronica Savu, Oscar Vazquez Mena, Mona Julia Katharina Klein, Céline Pahud
We fabricated amorphous silicon n-i-p solar cells with two types of nanopatterned back reflectors using stencil lithography. One reflector type has a plasmonic grating that is embedded in the ZnO layer; the other one has a metallic grating patterned on top ...
Ieee-Inst Electrical Electronics Engineers Inc2013Absorption enhancement in thin-film silicon solar cells
Thin-film silicon technology is a major candidate to comply with the ever-increasing global energy demand. The small thickness of silicon allows high industrial throughput and low material usage and subsequently opens new avenues to mass-production of low- ...
EPFL2013Nanocrystal-polymer nanocomposite electrochromic device
Raffaella Buonsanti, Anna Llordes Gil
Described is an electrochromic nanocomposite film comprising a solid matrix of an oxide based material, the solid matrix comprising a plurality of transparent conducting oxide (TCO) nanostructures dispersed in the solid matrix and a lithium salt dispersed ...
2013Stencil-nanopatterned back reflectors for thin-film amorphous silicon n-i-p solar cells
Jürgen Brugger, Christophe Ballif, Franz-Josef Haug, Andreea Veronica Savu, Oscar Vazquez Mena, Mona Julia Katharina Klein, Céline Pahud

Ieee2012Mild reactive stripping of coordinating ligands from nanocrystal surfaces using Meerwein's salt
Raffaella Buonsanti, Anna Llordes Gil
Native coordinating ligands acquired during the chem. synthesis of colloidal nanocrystals are optimized primarily for their ability to exert control over nanocrystal size, compn., morphol., and dispersibility, and not necessarily for their final applicatio ...
