Density control of GaN quantum dots on AlN single crystal

Nicolas Grandjean, Gordon Jens Callsen, Sebastian Pascal Tamariz Kaufmann

Full control over the density and emission properties of GaN quantum dots (QDs) should be feasible, provided that the growth proceeds in the Stranski-Krastanov (SK) growth mode. In this work, we derive the phase diagram for GaN QD formation on AlN by NH3-m ...

New refinement of the crystal structure of Zn(NH3)2Cl2 at 100 K

Arnaud Magrez, Trpimir Ivsic

The crystal structure of [ZnCl2(NH3)2], diamminedichloridozinc, was re-investigated at low temperature, revealing the positions of the hydrogen atoms and thus a deeper insight into the hydrogen-bonding scheme in the crystal packing. In comparison with pr ...

Annealing of Silicon Heterojunction Solar Cells: Interplay of Solar Cell and Indium Tin Oxide Properties

Christophe Ballif, Raphaël François Lemerle, Mathieu Gérard Boccard, Jan Haschke, Brahim Aissa

In this paper, we report the evolution of silicon heterojunction solar cell properties focusing, in particular, on the indium tin oxide (ITO) layers upon consecutive thermal annealing. We find that the charge carrier density

Effect of AlN seed layer on crystallographic characterization of piezoelectric AlN

Paul Muralt, Luis Guillermo Villanueva Torrijo, Annalisa De Pastina, Ramin Matloub Aghdam, Kaitlin Marie Howell, Waqas Bashir

Ultrathin aluminum nitride (AlN) films are of great interest for integration into nanoelectromechanical systems for actuation and sensing. Given the direct relationship between crystallographic texture and piezoelectric (PZE) response, x-ray diffraction ha ...

Dimensional tailoring of hydrothermally grown zinc oxide nanostructures in a continuous flow micro reactor

Martinus Gijs, Virendra Kumar Parashar

Dynamic deposition of ZnO nanostructures with varying morphologies (nanorods, nanocones, nanopencils, nanosheets, etc.), diameters, lengths and aerial densities on ITO-PET substrates has been achieved using a continuous flow microreactor in which we mainta ...

Nanocrystalline ZnO Obtained by the Thermal Decomposition of [Zn(H2O)(O2C5H7)(2)] in 1-Butanol: Synthesis and Testing as a Sensing Material

Thomas Maeder

The influence of conditions of heat treatment of a solution [Zn(H2O)(O2C5H7)(2)] in 1-butanol (temperature 125-185 degrees C, treatment times 2, 4, and 6 h) on dispersion and microstructure of the formed nanocrystalline and poorly aggregated zinc oxide, pr ...

Tuning adatom mobility and nanoscale segregation by twin formation and polytypism

Anna Fontcuberta i Morral, Federico Matteini, Gözde Tütüncüoglu, Luca Francaviglia

Nanoscale variations in the composition of an AlxGa1−xAs shell around a GaAs nanowire affect the nanowire functionality and can lead to the formation of localized quantum emitters. These composition fluctuations can be the consequence of variations of crys ...
