Institution: The student will be part of the Advanced Materials for Optoelectronics group, led by Dr. Annamaria Petrozza, at the Center for Nano Science and Technology (in Milan, partner with POLIMI) of the national-wide Istituto Italiano di Tecnologia.

Address: Via Raffaele Rubattino, 81, Milano 20134

Description: We do research on perovskite materials, a promising family of semiconductors. We focus on bridging the gap between their properties and their behavior as solar cells, LEDs, laser sources and photodetectors.

Project and skills acquired: The student will work on fabrication and characterization of perovskite devices for state-of-the-art X-ray detection. Perovskite materials excel in X-ray absorption due to large-Z elements in their composition (Sn, I, Cs, Pb, Bi), even for low thicknesses. This characteristic allows us to develop flexible and printed detectors. The student will acquire extensive knowledge on printing techniques (screen printing, blade coating) and other deposition methods (evaporation, photolithography). Additionally, she/he will have the opportunity to participate on the characterization of the detectors in a brand-new X-ray system tailored to this project. Moreover, she/he will have the possibility to focus on light-matter interaction, studying the photocarrier dynamics of the photodetector when excited with femtosecond laser sources.

Requirements: She/he has concluded, or is approaching the conclusion of, the master course, with excellent proven grades. She/he has strong interest in X-ray physics and/or photodetection. She/he is a proactive person with both good practical and theoretical skills. She/he is willing to learn and participate in cutting-edge research!
