Siliziumkarbid wird bei Anwendungen bis 25 kW und Spannungen bis 1200 V bis Ende des Jahrzehnts durch Galliumnitrid ersetzt. Diese These vertreten immer mehr Experten in der Leistungselektronik. Wir fragten bei Industrievertretern, Forschern und Analysten nach.

The "Integrated Quantum Photonics" group, led by Prof. Dr. Tim Schröder at Humboldt-Universität zu Berlin, has achieved a global first by creating and detecting photons with stable frequencies emitted from quantum light sources, specifically nitrogen-vacancy defect centers in diamond nanostructures.

Ferdinand-Braun-Institut (FBH) has developed the first GaN-based digital class-E outphasing power amplifier module for 5G base station applications in the 4 - 6 GHz range.

Lo sviluppo di una rete e di un internet quantistico ci permetteranno di compiere un enorme salto in avanti dal punto tecnologico, garantendo una trasmissione di dati ed una velocità di calcolo senza precedenti. Una tecnologia, purtroppo, non ancora priva di difetti, che il team "Integrated Quantum Photonics" sta cercando di risolvere.

Diamond material is of great importance for future technologies such as the quantum internet. Special defect centers can be used as quantum bits (qubits) and emit single light particles that are referred to as single photons.

A formidable obstacle to realising powerful LEDs emitting in the far UVC is the dominance of transverse magnetic polarisation that inhibits efficient light extraction. But this can be overcome with the introduction of compressively strained AlGaN quantum wells on annealed AlN templates, according to recent work by a team from Berlin.

Mikrowellen-Atmosphärendruck-Plasmaquelle zeigt gute Eignung zur Vorbehandlung von thermoplastischen Werkstoffen.

Was treibt junge Menschen an? Warum sind Vorbilder so wichtig zur Nachwuchsförderung? Und wie wird der Nachwuchs selbst zum Vorbild? Ein Schüler, eine junge Werkstattmeisterin und eine pensionierte Professorin machen deutlich, worauf es ankommt.

Scientists from the Berlin-based Ferdinand-Braun-Institut (FBH) will develop the required diode lasers and quantum light modules for the recently launched Quantum‐Enhanced Early Diagnostics (QEED) project, funded by the German Federal Ministry of Education and Research. The project aims to develop a novel approach to quickly detect and fight cancer.

Herz und Atmung kontaktlos messen – an dieser medizinischen Revolution forschen gerade Wissenschaftler am CTK in Cottbus. So ist der aktuelle Stand und was das für Patienten bedeutet.

The Ferdinand-Braun-Institut (FBH) will present its latest developments in diode lasers and UV LEDs at Photonics West 2023 in San Francisco (28th January to 2nd February).

Dr. Björn Globisch will die Forschungs- und Entwicklungsarbeit im Unternehmen weiter voranbringen.
