Jobbeschreibung

Overview

The Leibniz-Institut für Kristallzüchtung (IKZ) is a leading research institution in science & technology as well as service & transfer of crystalline materials. Our goal is to enable solutions for urgent societal challenges (e.g. communication, artificial intelligence, climate protection, health) by modern electronic & photonic technologies. The institute is part of Forschungsverbund Berlin and a member of the Leibniz Association. More details are available on the institute webpage: ikz-berlin.de.

PhD Student Position (m/f/d) for the Marie Skłodowska-Curie Doctoral Network HINA

Hybrid INtegration of Alkaline niobate - tantalate films for advanced photonic and piezoelectric devices

The HINA project proposes the hybrid integration of alkaline niobate-tantalate thin films (materials with high electro-optic, nonlinear, piezoelectric, elasto-optic coefficients) in photonic and acoustic devices for advanced semiconductor photonics platforms. HINA links world‑leading research groups at Academia and Industry to provide an integrated approach of synthesis/fabrication, characterization, modeling/theory, linked to concepts for materials integration in devices and systems. The MSCA Doctoral Network HINA offers 18 PhD positions.

Responsibilities

• Epitaxial growth of KNN films by CVD with different surface orientations for SAW and electro-optical devices
• Optimization of growth conditions for epitaxially strained, stoichiometric (K,Na)(Nb,Ta)O3 films by MOVPE using commercial or designed MO precursors
• Influence of lattice strain, Na/K ratio, Nb/Ta and off-stoichiometry (alkaline deficiency or niobium deficiency) on piezoelectric properties and domain formation
• Variation of film direction by using differently oriented oxide substrates and textured electrodes
• Revealing structure-properties relationship with focus on K2 (SAW, BAW) and electro-optic properties

Supervisor: Dr. Jutta Schwarzkopf; Contact: [e-mail]

Eligibility

To be eligible the applicant has to fulfil the trans-national mobility criterion, i.e. not have resided or carried out their main activity in Germany for more than 12 months in the 36 months immediately before the recruitment date, unless as part of a compulsory national service or a procedure for obtaining refugee status under the Geneva Convention. In addition, the applicant has to be – at the date of recruitment – a doctoral candidate (i.e. not already in possession of a doctoral degree). Researchers who have successfully defended their doctoral thesis but have not yet formally been awarded the doctoral degree will not be considered eligible.

What we offer

This is a full-time position (39 hours per week) with 3 years duration, to start as soon as possible. For the salary of the Marie Skłodowska-Curie PhDs in Germany the European Commission provides a monthly Living Allowance of 3,342.20 € plus a monthly Mobility Allowance of 600 €. Researchers who have or acquire family obligations during their employment are also awarded a monthly Family Allowance of 660 €. Please note that the combined amounts form the monthly gross employer salary, which is subject to deductions and taxes as per national law. The monthly gross salary varies, depending on personal circumstances, and amounts to approximately 3,250–3,800 € (without family allowance/with family allowance). Family is defined as persons linked to the researcher by marriage, a relationship with equivalent status, or dependent children who are actually being maintained by the researcher. A Special Needs Allowance might be awarded to recruited researchers with disabilities whose impairments make participation in the action not possible without such items or services.

We offer the usual social benefits (30 vacation days in a 5-day week, flexible working hours). IKZ is an equal opportunity employer and actively supports reconciliation of work and family life. There is equality for applicants of all genders. Qualified women are especially encouraged to apply. Among equally qualified applicants, preference will be given to disabled candidates.
