Monitoring Charge Carrier Dynamics at Atomic Length Scales by STM-induced Luminescence

Christoph Grosse

The goal of this thesis is the combination of the high spatial resolution of scanning tunneling microscopy (STM) with the high temporal resolution of optical spectroscopy, by monitoring the light emitted from the tunnel junction. Two complementary techniqu ...

First-principles investigation of organic photovoltaic materials C-60, C-70, [C-60]PCBM, and bis-[C-60]PCBM using a many-body G(0)W(0)-Lanczos approach

Nicola Marzari, Paolo Umari

We present a first-principles investigation of the excited-state properties of electron acceptors in organic photovoltaics including C-60, C-70, [6,6]-phenyl-C-61-butyric-acid-methyl-ester ([C-60] PCBM), and bis-[C-60] PCBM usingmany-body perturbation theo ...

A Close Look at Charge Generation in Polymer:Fullerene Blends with Microstructure Control

Jacques-Edouard Moser, Natalie Renuka Banerji, Mariateresa Scarongella, Jelissa Risse, Natalie Stingelin

We reveal some of the key mechanisms during charge generation in polymer:fullerene blends exploiting our well-defined understanding of the microstructures obtained in pBTTT:PCBM systems via processing with fatty acid methyl ester additives. Based on ultraf ...

Graphitic carbon in a nanostructured titanium oxycarbide thin film to improve implant osseointegration

Giovanni Longo

A nanostructured coating layer on titanium implants, able to improve their integration into bones and to protect against the harsh conditions of body fluids, was obtained by Ion Plating Plasma Assisted, a method suitable for industrial applications. A tita ...

The influence of microstructure on charge separation dynamics in organic bulk heterojunction materials for solar cell applications

Jacques-Edouard Moser, Natalie Renuka Banerji, Arun Aby Paraecattil, Mariateresa Scarongella, Natalie Stingelin

Light-induced charge formation is essential for the generation of photocurrent in organic solar cells. In order to gain a better understanding of this complex process, we have investigated the femtosecond dynamics of charge separation upon selective excita ...

Diyne-Functionalized Fullerene Self-Assembly for Thin Film Solid-State Polymerization

Jakob Heier, Gaëtan Wicht, Raffaele Mezzenga

C-60 fullerene derivatives bearing aliphatic chains can self-assemble into versatile supramolecular structures. Cross-linking of such self-assembled morphologies is an attractive approach to enhance the structural stability of these self-organized structur ...

Translational dynamics of photoexcited atoms in 4He nanodroplets: the case of silver

Alberto Hernando de Castro, Marcel Drabbels, Evgeniy Loginov

The dynamics following the photoexcitation of Ag atoms in 4He nanodroplets via the 5p 2P1=2 ← 5s2S1=2 and 5p 2P3=2 ← 5s2S1=2 transitions has been investigated in a joint experimental and theoretical effort. It has been experimentally found that upon excita ...
