Fabrication and Characterization of Quantum-LEDs

What it is about

In the internship, you fabricate quantum LEDs based on III-V quantum dots and characterize them electrically and optically. After a theoretical introduction, you perform all microfabrication steps in the cleanroom yourself and finally demonstrate that the components emit individual photons.

What you will be able to do

Evaluate theoretical foundations of single-photon sources
Assess applications in quantum technologies
Understand production of semiconductor quantum dots by MBE
Apply microfabrication of diode structures in III-V semiconductors
Characterize electrical and optical quantum technology components
Evaluate the metric of individual photons using HBT measurements

What the module consists of

PraktikumCarrying out all microfabrication steps in the cleanroom as well as electrical and optical measurements
Theoretische EinweisungPreparation for the practical work

Teaching method

Praktisches Arbeiten im Laborto practically learn fabrication and characterization
Auswertung der Messdatento interpret and document measurement results
Anfertigen eines Berichtsfor reflection and assessment of the work performed
