J-aggregation induced low bandgap anthracene-based conjugated molecule for solution-processed solar cells.

Chemical communications (Cambridge, England)

Shin J, Kang NS, Kim KH, Lee TW, Jin JI, Kim M, Lee K, Ju BK, Hong JM, Choi DH.
PMID: 22801585
Chem Commun (Camb). 2012 Sep 04;48(68):8490-2. doi: 10.1039/c2cc34109c. Epub 2012 Jul 17.

A new anthracene-based X-shaped conjugated molecule, HBTATHT, was synthesized. Thin film transistors based on unannealed HBTATHT showed a carrier mobility of 0.15 cm(2) V(-1) s(-1) (I(on/off) = 7.9 × 10(6)). Further, a solution processed solar cell made of HBTATHT...

Carrier envelope offset frequency of a doubly resonant, nondegenerate, mid-infrared GaAs optical parametric oscillator.

Optics letters

Lee KF, Jiang J, Mohr C, Bethge J, Fermann ME, Leindecker N, Vodopyanov KL, Schunemann PG, Hartl I.
PMID: 23595427
Opt Lett. 2013 Apr 15;38(8):1191-3. doi: 10.1364/OL.38.001191.

We measure the carrier envelope offset (CEO) frequency of the mid-infrared frequency comb (wavelength tunable between 3 and 6 μm) from a doubly resonant nondegenerate synchronously pumped optical parametric oscillator (SPOPO) as a function of the CEO frequency of...

Reliable metal deposition into TiO(2) nanotubes for leakage-free interdigitated electrode structures and use as a memristive electrode.

Angewandte Chemie (International ed. in English)

Liu N, Lee K, Schmuki P.
PMID: 24123424
Angew Chem Int Ed Engl. 2013 Nov 18;52(47):12381-4. doi: 10.1002/anie.201306334. Epub 2013 Oct 02.

Nearly 100 % filling of TiO2 nanotubes with metals, including Ag, Cu, Au, and Pt, was achieved by defect-sealing treatment at the bottom of the nanotubes, followed by metal deposition using nuclei formation/coalescence. The resulting short-circuit-free interdigitated electrode configurations...
