Humboldt-Universitat Zu Berlin


The Humboldt-Universität zu Berlin, Germany, ( was founded in 1810, and is today one of eleven “Universities of Excellence” in Germany.

The HU Berlin is divided into 11 faculties with 419 professorships, with 53 special professorships and 14 endowed chairs and professorships in cooperation projects, and 1,825 lectureships and research assistantships.

About 31,000 students are enrolled at HU Berlin.

The university commands a budget of € 339.4m excluding non-governmental grants.



  • Role in the project

Humboldt-Universität zu Berlin will be involved in WP4 “Integration with photonic technologies”, with the goal of developing high-grade epitaxial GaP membranes that can be fabricated into photonic crystal devices and integrated with graphene.


P.I. - Prof. Dr. Fariba Hatami

The research of Fariba Hatami is dedicated to development of novel semiconductor systems, particularly strained heterostructures and quantum structures, for opto-electronic device application, such as single photon and light emitters, detectors, wave guides, and resonators. The results are published in several patent disclosures and more than 60 refereed papers. Internationally renowned results include the first report on photoluminescence of GaSb/GaAs quantum dots, and the first report on LEDs based on InP/GaP quantum dots. During her PhD she demonstrated for the first time the light emission from InP/GaP quantum dots. As a Feodor Lynen Fellow at Stanford University from 2003-2005 she gained experience in antimonide-based and dilute III-V nitride quantum structures. Since 2006 she is a senior researcher at Humboldt-Universität zu Berlin.

Research Team description
The research team has extensive experience and internationally acknowledged expertise in the design, fabrication, and investigation of semiconductor heterostructures. An important component is the materials science and the growth of III-V heterostructures using gas-source molecular-beam epitaxy. In the frame of the research project GRASP the group aims to develop novel hybrid structures that efficiently interface existing photonic technologies with graphene plasmons. The efforts will focus on developing high-grade photonic-crystal cavities based on GaP membranes. Preliminary experiments with GaP photonic crystal cavities indicate hundred-fold enhancement of the interaction between graphene and light, as compared to a single-pass transmission configuration (Nano Lett. 12, 5626).
