Optical–Structural Probe of Perovskite Films (4D-STEM)

AMOLF; Amsterdam; On-site; EUR 46,000 - 55,000; Full time

Benefits offered by this job

Housing assistance

Transport cost reimbursement

Job summary

AMOLF in Amsterdam invites applications for a postdoctoral researcher in the Hybrid Nanosystems group. The project investigates whether atomic structure and defects in halide perovskite films can be inferred from optical measurements, using PL, absorption, and TEM data.

You will collaborate with the HELIOS and SHINE facilities to train a neural network that links light to structure, contributing to solar-energy materials research.

Qualifications

• PhD in physics, materials science, nanoscience, or related field.
• Experience with TEM on halide perovskites or beam-sensitive materials is a strong plus.
• Experience with optical spectroscopy, data analysis in Python, or machine learning is an advantage.

Responsibilities

• High-throughput PL screening with the HELIOS team to identify atomic structures with interesting properties.
• Correlative structural and optical mapping combining 4D-STEM with PL and absorption on TEM grids.
• In situ TEM under laser excitation to reproduce transient or metastable states.
