Diamond for infrared optoelectronics: time-resolved spectroscopy of excited acceptor states in diamond

Hübers, Heinz-Wilhelm, Prof. Dr. rer. nat. habil. (Optical Systems)

Duration of Project: 11/2017 - 10/2020

The project is devoted to the experimental investigation of excited states in boron-doped diamond crystals. The lifetimes of the excited states will be determined by mid-infrared pump-probe spectroscopy and time-resolving Fourier transform infrared a ...

DFG-NSF-Materials World Network:: Spin phenomena in quasi-1D systems of narrow-gap semiconducters

Fischer, Saskia, Prof. Dr. rer. nat. (New Materials)

Duration of Project: 01/2011 - 10/2014

In den letzten zehn Jahren ist sehr intensiv Grundlagenforschung zu Spin-Effekten in Halbleitern und Halbleiternanostrukturen vorangetrieben worden, motiviert durch die Möglichkeit eine neue Ära in der Elektronik ("Spinelektronik") und Informationste ...

Compressed Sensing in Ptychography and Transmission Electron Microscopy

Van den Broek, Wouter, (Experimental Physics / Structural Research and Electron Microscopy)

Duration of Project: 07/2017 - 03/2021

This project uses compressed sensing to improve object retrieval from ptychographic data sets consisting out of HRTEM images and diffraction patterns, and to speed up data recording and thus decrease electron dose and specimen damage. More specifical ...

Charge separation at nanostructured molecular donor-acceptor interfaces

Koch, Norbert, Prof. Dr. techn. (Structure, Dynamics and electronic Properties of Molecular Systems)

Duration of Project: 09/2010 - 08/2012

This project seeks to unravel the electronic structure of conjugated organic molecules on conductive surfaces and at heterointerfaces by means of photoelectron spectroscopy. Specifically, parameters of importance for photovoltaic cells like hole and ...

Ballistischer Wärmetransport in dünnen und ultradünnen Oxidschichten

Fischer, Saskia, Prof. Dr. rer. nat. (New Materials)

Duration of Project: 12/2016 - 06/2020
