Milanov AP, Xu K, Cwik S, Parala H, de los Arcos T, Becker HW, Rogalla D, Cross R, Paul S, Devi A.

Dalton Trans. 2012 Dec 07;41(45):13936-47. doi: 10.1039/c2dt31219k. Epub 2012 Oct 01.

Alternative novel precursor chemistries for the vapor phase deposition of rare-earth (RE) oxide thin films were developed by synthesising the homoleptic guanidinate compounds tris(N,N'-diisopropyl-2-dimethylamidoguanidinato)-scandium(III) [Sc(DPDMG)(3)] (1), tris(N,N'-diisopropyl-2-dimethylamidoguanidinato)-erbium(III), [Er(DPDMG)(3)] (2) and tris(N,N'-diisopropyl-2-dimethylamidoguanidinato)-yttrium(III), [Y(DPDMG)(3)] (3). All three compounds are monomeric as...

Modeling of Spatially Correlated Energetic Disorder in Organic Semiconductors.

Journal of chemical theory and computation

Kordt P, Andrienko D.
PMID: 26588022
J Chem Theory Comput. 2016 Jan 12;12(1):36-40. doi: 10.1021/acs.jctc.5b00764. Epub 2015 Dec 15.

Mesoscale modeling of organic semiconductors relies on solving an appropriately parametrized master equation. Essential ingredients of the parametrization are site energies (driving forces), which enter the charge transfer rate between pairs of neighboring molecules. Site energies are often Gaussian-distributed...

Excited States of Dicyanovinyl-Substituted Oligothiophenes from Many-Body Green's Functions Theory.

Journal of chemical theory and computation

Baumeier B, Andrienko D, Ma Y, Rohlfing M.
PMID: 26593361
J Chem Theory Comput. 2012 Mar 13;8(3):997-1002. doi: 10.1021/ct2008999. Epub 2012 Mar 02.

Excited states of dicyanovinyl-substituted oligothiophenes are studied using many-body Green's functions theory within the GW approximation and the Bethe-Salpeter equation. By varying the number of oligomer repeat units, we investigate the effects of resonant-antiresonant transition coupling, dynamical screening, and...

Winners always win: growth of a wide range of plant species from low to future high CO2.

Ecology and evolution

Temme AA, Liu JC, Cornwell WK, Cornelissen JH, Aerts R.
PMID: 26640673
Ecol Evol. 2015 Oct 15;5(21):4949-61. doi: 10.1002/ece3.1687. eCollection 2015 Nov.

Evolutionary adaptation to variation in resource supply has resulted in plant strategies that are based on trade-offs in functional traits. Here, we investigate, for the first time across multiple species, whether such trade-offs are also apparent in growth and...

Androgen receptor DNA binding and chromatin accessibility profiling in prostate cancer.

Genomics data

Nevedomskaya E, Stelloo S, van der Poel HG, de Jong J, Wessels LF, Bergman AM, Zwart W.

In this work, the influence of micro- and macro-deformation profiles in GaN nanowires (NWs) on the angular intensity distribution of X-ray diffraction are studied theoretically. The calculations are performed by using kinematical theory of X-ray diffraction and assuming the...

Band structure engineering in organic semiconductors.

Science (New York, N.Y.)

Schwarze M, Tress W, Beyer B, Gao F, Scholz R, Poelking C, Ortstein K, Günther AA, Kasemann D, Andrienko D, Leo K.
PMID: 27313043
Science. 2016 Jun 17;352(6292):1446-9. doi: 10.1126/science.aaf0590.

A key breakthrough in modern electronics was the introduction of band structure engineering, the design of almost arbitrary electronic potential structures by alloying different semiconductors to continuously tune the band gap and band-edge energies. Implementation of this approach in...

Design rules for organic donor-acceptor heterojunctions: pathway for charge splitting and detrapping.

Journal of the American Chemical Society

Poelking C, Andrienko D.

J Am Chem Soc. 2015 May 20;137(19):6320-6. doi: 10.1021/jacs.5b02130. Epub 2015 May 07.

Organic solar cells rely on the conversion of a Frenkel exciton into free charges via a charge-transfer state formed on a molecular donor-acceptor pair. These charge-transfer states are strongly bound by Coulomb interactions and yet efficiently converted into charge-separated...
