Multicolour Optical Coding from a Series of Luminescent Lanthanide Complexes with a Unique Antenna

The bis-tetrazolate-pyridine ligand H2pytz sensitises efficiently the visible and/or near-IR luminescence emission of ten lanthanide cations (Pr, Nd, Sm, Eu, Tb, Dy, Ho, Er, Tm, Yb). The LnIII complexes present sizeable quantum yields in both domains with ...

Structural and optical properties of the Cu2ZnSnSe4 thin films grown by nano-ink coating and selenization

Jürgen Brugger, Ying Liu

Quaternary semiconductor Cu2ZnSnSe4 (CZTSe) is a very promising alternative to semiconductors based on indium (In) and gallium (Ga) as solar absorber material due to its direct band gap, inherent high absorption coefficient (> 10(4) cm(-1)) and abundance o ...

Excitation of Coherent Phonons in the One-Dimensional Bi(114) Surface

Jan Hugo Dil

We present time-resolved photoemission experiments from a peculiar bismuth surface, Bi(114). The strong one-dimensional character of this surface is reflected in the Fermi surface, which consists of spin-polarized straight lines. Our results show that the ...

Origin of Rashba splitting in the quantized subbands at the Bi2Se3 surface

Klaus Kern, Christian Reinhard Ast

We study the band structure of the Bi2Se3 topological insulator (1 1 1) surface using angle-resolved photoemission spectroscopy. We examine the situation where two sets of quantized subbands exhibiting different Rashba spin splitting are created via bendin ...

Evidence of reduced surface electron-phonon scattering in the conduction band of Bi2Se3 by nonequilibrium ARPES

Klaus Kern, Marco Grioni, Helmuth Berger, Philippe Bugnon, Alberto Crepaldi, Jens Christian Johannsen

The nature of the Dirac quasiparticles in topological insulators calls for a direct investigation of the electron-phonon scattering at the surface. By comparing time-resolved ARPES measurements of the topological insulator Bi2Se3 with different probing dep ...

Elemental Topological Insulator with Tunable Fermi Level: Strained alpha-Sn on InSb(001)

Jan Hugo Dil

We report on the epitaxial fabrication and electronic properties of a topological phase in strained alpha-Sn on InSb. The topological surface state forms in the presence of an unusual band order not based on direct spin-orbit coupling, as shown in density ...

Advantages of highly ionized pulse plasma magnetron sputtering (HIPIMS) of silver for improved E-coli inactivation

César Pulgarin, Juan Kiwi, Rosendo Sanjines, Oualid Baghriche

This study addresses the DC-magnetron sputtering (DCMS) of Ag-films on polyester and compares the results found for the E. coli inactivation with the inactivation obtained when applying highly ionized pulse plasma power magnetron sputtering (HIPIMS). The a ...

Phonon dynamics in CuxBi2Se3 (x=0, 0.1, 0.125) and Bi2Se2 crystals studied using femtosecond spectroscopy

Jia Liu, Helmuth Berger

Phonon dynamics in Bi, Bi2Se2, and CuxBi2Se3 (x=0, 0.1, 0.125) single crystals was investigated using femtosecond pump-probe spectroscopy. Two damped oscillations in measured transient reflectivity changes were observed, respectively, attributed to coheren ...

Gate-controlled linear magnetoresistance in thin Bi2Se3 sheets

Klaus Kern, Marko Burghard, Pascal Gehring

We explore the emergence of linear magnetoresistance in thin Bi2Se3 sheets upon tuning the carrier density using a back gate. With increasingly negative gate voltage, a pronounced magnetoresistance of similar to 100% is observed, while the associated B-fie ...

Electronic, vibrational, and transport properties of pnictogen-substituted ternary skutterudites

Nicola Marzari, Boris Kozinsky

First principles calculations are used to investigate electronic band structure and vibrational spectra of pnictogen-substituted ternary skutterudites. We compare the results with the prototypical binary composition CoSb3 to identify the effects of substit ...
