Vardeny, Zeev Valentine | Below-gap excitation of ∏-conjugated polymer-fullerene blends: implications for bulk organic heterojunction solar cells | We used a variety of optoelectronic techniques such as broadband fs transient and cw photomodulation spectroscopies, electroabsorption, and short-circuit photocurrent in bulk heterojunctions organic solar cells for studying the photophysics in ∏-conjugated polymer-fullerene blends with below-gap... | pi-conjugated polymers; Fullerene blends; Below-gap excitations; Bulk heterojunctions; Bulk organic heterojunction solar cells; Photophysics | 2008-07 |

Goller, Franz | Dynamical origin of spectrally rich vocalizations in birdsong | Birdsong is a model system for learned vocal behavior with remarkable parallels to human vocal development and sound production mechanisms. Upper vocal tract filtering plays an important role in human speech, and its importance has recently also been recognized in birdsong. However, the mechanisms... | Taeniopygia guttata; Labial oscillations; SNILC bifurcation | 2008-07 |

Gerton, Jordan | Nanoscale fluorescence microscopy using carbon nanotubes | We demonstrate the use of single-walled carbon nanotubes as nano-optical probes in apertureless near-field fluorescence microscopy. The carbon nanotubes strongly quench fluorescence leading to near-field contrast with spatial resolution of ~20 nm. | 2008-07 | |

Boehme, Christoph | Spin-dependent processes at the crystalline Si-SiO2 interface at high magnetic fields | An experimental study on the nature of spin-dependent excess charge-carrier transitions at the interface between (111)-oriented phosphorous-doped ([P]) ~ 1015 cm−3) crystalline silicon and silicon dioxide at high magnetic field (B0~8.5 T) is presented. Electrically detected magnetic-resonance (E... | Silicon interfaces; Spin-dependent recombination | 2008-07 |
