Multiexciton dynamics in tailored band-gap quasi-one-dimensional systems

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Justyna Szeszko

Optoelectronic properties of site-controlled AlGaAs/GaAs quasi-one-dimensional structures are investigated. Controllable linear variation of the band gap along the vertical axis of the quantum wire, symmetrical with respect to its center, results in a set ...

Automated reconstruction of E-coli metabolic network from labeled metabolites

Vassily Hatzimanikatis, Jasmin Maria Hafner, Noushin Hadadi

Biological pathways have been extensively analyzed and modeled in respect to overall conversions of substrates to products, although information on atom transitions or atom flow in metabolic networks is not available in databases. The reaction atom mapping ...

Direct measurement of the bulk spin structure of noncentrosymmetric BiTeCl

Jan Hugo Dil, Stefan Peter Muff

A strong spin-orbit interaction leads to a Rashba-type splitting of the bulk bands of BiTeCl, which results in toroidal Fermi surfaces with distinct spin structures depending on the chemical potential. Here, we present spin-and angle-resolved photoelectron ...

Interfacial Ga-As suboxide: Structural and electronic properties

Alfredo Pasquarello, Davide Colleoni

The structural and electronic properties of Ga-As suboxide representative of the transition region at the GaAs/oxide interface are studied through density functional calculations. Two amorphous models generated by quenches from the melt are taken under con ...

Rational design of triazatruxene-based hole conductors for perovskite solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Kasparas Rakstys

Triazatruxene core based hole transporting materials (HTMs), HMDI (5,10,15-trihexyl-3,8,13-trimethoxy-10,15-dihydro-5H-diindolo[3,2-a: 3',2'-c]carbazole) and HPDI (5,10,15-tris(4-(hexyloxy)phenyl)-10,15-dihydro-5H-diindolo[3,2-a: 3',2'-c]carbazole) were sy ...

Defect levels at GaAs/Al2O3 interfaces: As-As dimer vs. Ga dangling bond

Alfredo Pasquarello, Giacomo Francesco Leonardo Miceli

Charge transition levels of the As-As dimer and the Ga dangling bond at GaAs/Al2O3 interfaces are determined through density-functional calculations. The same parent interface model structure is used as a starting point for creating both defects providing ...

Two-Level Discretization Techniques For Ground State Computations Of Bose-Einstein Condensates

Patrick Henning

This work presents a new methodology for computing ground states of Bose-Einstein condensates based on finite element discretizations on two different scales of numerical resolution. In a preprocessing step, a low-dimensional (coarse) generalized finite el ...

Magnetic nano-fluctuations in a frustrated magnet

Henrik Moodysson Rønnow, Ivica Zivkovic, Joël Mesot, Martin Mansson, Krunoslav Prsa

Frustrated systems exhibit remarkable properties due to the high degeneracy of their ground states. Stabilised by competing interactions, a rich diversity of typically nanometre-sized phase structures appear in polymer and colloidal systems, while the surf ...

Atomic-Scale Observation of Multiconformational Binding and Energy Level Alignment of Ruthenium-Based Photosensitizers on TiO2 Anatase

Klaus Kern, Christian Alexander Stephan Dette, Stephan Rauschenbach, Sebastian Stepanow, Feliciano Giustino, Gordon Rinke, Christopher Seiji Kley

Dye-sensitized solar cells constitute a promising approach to sustainable and low-cost solar energy conversion. Their overall efficiency crucially depends on the effective coupling of the photosensitizers to the photoelectrode and the details of the dye's ...
