Paul-Drude-Institut für Festkörperelektronik

Paul-Drude-Institut für Festkörperelektronik (PDI) is a research institute in Berlin, Germany. We perform basic and applied research at the nexus of materials science, condensed matter physics, and device engineering.

The institute is part of the Forschungsverbund Berlin and a member of the Leibniz Association.

Nanonarratives: John W. Freeland, Guest Scientist

01/19/2024 / Interviews

John W. Freeland, a senior physicist and staff scientist at Argonne National Laboratory, is a specialist in soft X-ray spectroscopy and supports scientists using the Advanced Photon Source (APS). As the APS is currently undergoing an intensive upgrade, John seized the opportunity to take a sabbatical and join us at PDI. Here he shares his thoughts about the experience.

At PDI, we recognize the profound importance of scientific outreach in fostering a connection between the research community and the world outside. In this article, we discuss why engaging with the community is so important for scientific institutions like ours.

PDI is currently building up an application laboratory for time-resolved cathodoluminescence spectroscopy, where the detectors will be optimized for ultraviolet wavelengths down to about 180 nm. The system will be capable of measuring classic…

Microcavity exciton-polaritons (polaritons) are light-matter quasi-particles arising from the strong coupling of photons and quantum well excitons in a semiconductor microcavity. Polaritons are composite bosons with µm-sized thermal de-Broglie wavelengths…

This project aims at the realization of hybrid quantum systems based on the coupling of single electrons and single phonons in the form of acoustic waves in tailored nanostructures. Our focus is the study of the electron-phonon interaction in systems…

The key objective of this project is the development of integrated terahertz quantum-cascade lasers for high-resolution spectroscopy and future space applications at 3.5 THz and 4.7 THz. These two frequencies are very important for the detection of the OH…

This project aims to provide new experimental insights into the formation and impact of point defects in Ga2O3. We approach this challenge by cross-linking different experimental characterization techniques, such as micro-Raman spectroscopy and…

Aharonov-Bohm spectroscopy is a powerful tool to study the quantum statistics of quasi particles in the integer and fractional quantum Hall regimes. Related major activities are in particular driven by the search for non-abelian states which could pave…
