Paul-Drude-Institut für Festkörperelektronik Leibniz-Institut im Forschungsverbund Berlin e. V.

The Paul Drude Institute is part of the Forschungsverbund Berlin e.V. and a member of the Leibniz Association. The institute carries out basic and applied research at the nexus of materials science, condensed matter physics, and device engineering. In the Epitaxy department at PDI, a dedicated team of scientists, technicians, postdocs, and students operates 13 MBE systems for the synthesis of a wide range of material systems, including arsenides, nitrides, oxides, and 2D materials. This in-house collaborative environment offers abundant opportunities for both direct and indirect learning in various MBE technologies, making it an ideal place to start a career in the field.

Distributed polarization doping of group-III nitride alloys by molecular beam epitaxy

Working field:

Wurtzite group III-nitride semiconductor heterostructures exhibit strong spontaneous and piezoelectric polarization fields on the order of a few MV/cm along the polar c-axis. As electrostatics dictates, when polarization changes in space, corresponding polarization charges are induced at those locations. These polarization charges can be utilized for band diagram engineering of polar-nitride heterostructures for various purposes, including 2D electron gas formation and tunnel junctions. In this MSc thesis study, the successful candidate will work on distributed polarization doping of group-III nitride alloys to develop optimal growth recipes for such alloys at PDI. If time permits, an attempt will be made to demonstrate a polarization-induced dopant-free graded AlxGa1-xN p-n junction.

Requirements:

  • Bachelor degree in physics, electrical engineering, materials science, or a related field;
  • Courses in semiconductor physics, nanotechnology, or a related subject are advantageous.

What we offer:

  • Modern laboratories with a wide range of experimental techniques
  • Supportive environment with experts for various scientific sub-fields and a low number of students per advisor
  • International and culturally diverse community
  • Location in the heart of Berlin with excellent public transport connections
