Postdoc position (mfd) Growth and characterization of complex oxide thin film heterostructures with quantum confined itinerant carriers

The discovery of a two-dimensional electron gas (2DEG) at the interface between SrTiO3
and LaAlO3 laid fertile ground to develop innovative device concepts in electronics
quantum physics and most recently spin-orbitronics by harnessing the Rashba
spin-orbit coupling (SOC). Desirable properties such as long spin diffusion length
and efficient spin-charge interconversion require the synthesis of high-quality
oxide heterostructures to enable exploitation of these spin-orbitronic functionalities
at room temperature. The goal is to synthesize stannate titanate and
tantalite-based heterostructures forming low-dimensional electron and hole gases.
This will be accomplished by exploring the growth parameter space and utilizing
conventional plasma-assisted as well as hybrid molecular beam epitaxy.
The postdocs research will benefit from interactions with ongoing research
activities at PDI within the CReA Novel Oxides as well as from the international
collaborations. Additional responsibilities may include mentoring graduate
and undergraduate students as well as contributing to grant proposals and project reports.

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 the Epitaxy department at PDI
a dedicated team of scientists technicians postdocs and students operates a dozen
molecular beam epitaxy systems for the synthesis of a wide range of material systems
including arsenides nitrides oxides and 2D materials. This collaborative environment
offers abundant opportunities for learning about various aspects of epitaxy making it
an ideal place to start a career in this field.

With approximately 100 employees and more than 15 nationalities PDI is committed
to building a talented inclusive and culturally diverse workforce. We understand that
our shared future is guided by basic principles of fairness and mutual respect.

As anequal opportunity and family-friendly employer we offer highly flexible
employment conditions such as flexible working hours parental leave and
home office and we strive to create a family- and life-conscious working environment.

Among equally qualified applicants preference will be given to candidates from
marginalized groups. That means we welcome every qualified application regardless
of sex and gender origin nationality religion belief health and disabilities age or
sexual orientation.

PDI follow our gender equality plan so we want to engage women* to apply at
PDI to balance the gender ratio in science. Disabled applicants with equal qualification
and aptitude will be given preferential consideration.
