Harnessing Topological Band Effects in Bismuth Telluride Selenide for Large Enhancements in Thermoelectric Properties through Isovalent Doping

Klaus Kern, Marko Burghard, Pascal Gehring, Alexander Ronald Hoyer, Kristina Vaklinova

Dilute isovalent sulfur doping simultaneously increases electrical conductivity and Seebeck coefficient in Bi2Te2Se nanoplates, and bulk pellets made from them. This unusual trend at high electron concentrations is underpinned by multifold increases in ele ...

Significance of surface charge and shell material of superparamagnetic iron oxide nanoparticle (SPION) based core/shell nanoparticles on the composition of the protein corona

Heinrich Hofmann, Lionel André Maurizi, Morteza Mahmoudi, Géraldine Sylvie Coullerez, Usawadee Sakulkhu

As nanoparticles (NPs) are increasingly used in many applications their safety and efficient applications in nanomedicine have become concerns. Protein coronas on nanomaterials' surfaces can influence how the cell "recognizes" nanoparticles, as well as the ...

Wetting of Ga on SiOx and Its Impact on GaAs Nanowire Growth

Federico Matteini, Heidi Andrea Potts, Fauzia Jabeen

Ga-assisted growth of GaAs nanowires on silicon provides a path for integrating high-purity III-Vs on silicon. The nature of the oxide on the silicon surface has been shown to impact the overall possibility of nanowire growth and their orientation with the ...

Femtosecond-laser hyperdoping silicon in an SF6 atmosphere: Dopant incorporation mechanism

Tobias Schneider, Silvija Gradecak

In this paper, we examine the fundamental processes that occur during femtosecond-laser hyperdoping of silicon with a gas-phase dopant precursor. We probe the dopant concentration profile as a function of the number of laser pulses and pressure of the dopa ...

Metal free sensitizer and catalyst for dye sensitized solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Ladislav Kavan

The carbon neutral process for energy conversion is of utmost importance, in this context photovoltaics, especially dye sensitized solar cells (DSSCs) are a viable alternative. Few terawatts of carbon free renewable energy can be produced by DSSCs. However ...

Enhanced tunneling conductivity induced by gelation of attractive colloids

Peter Ryser, Claudio Grimaldi, Francesco Varrato, Giuseppe Foffi, Biagio Nigro

We show that the formation of a gel by conducting colloidal particles leads to a dramatic enhancement in bulk conductivity, due to interparticle electron tunneling, combining predictions from molecular-dynamics simulations with structural measurements in a ...

Thermal conductivity and interfacial conductance of AlN particle reinforced metal matrix composites

Andreas Mortensen, Christian Monachon, Ludger Weber, Masahiro Kida

Aluminum nitride (AlN) particle reinforced metal-matrix-composites produced by pressure infiltration are characterized in terms of their thermal conductivity. The composites are designed to cover a wide range of phase contrast between the dispersed particl ...
