Ionic Transport and Dynamic Processes in Perovskite Thin-Film Devices

Metal halide perovskites have emerged as a versatile semiconductor platform for applications including photovoltaics, light-emitting diodes, photodetectors, and electronic devices. Beyond their excellent optoelectronic properties, these materials exhibit significant ionic mobility, leading to a rich set of dynamic phenomena such as transient electrical responses, memory effects, and non-equilibrium transport processes. While these effects are often associated with performance limitations, they also provide exciting opportunities to engineer novel device functionalities and adaptive material systems.

In this project, you will investigate ionic transport phenomena in perovskite thin-film devices and explore how these processes can be influenced through different external stimuli. Device fabrication will be carried out using imec's state-of-the-art research infrastructure, including microfabrication facilities and dedicated thin-film materials laboratories. You will gain hands-on experience in cleanroom processing techniques such as photolithography, thin-film deposition, encapsulation, and device integration.

Following fabrication, the devices will be characterized using a broad range of electrical and optical measurement techniques, including current-voltage measurements, transient electrical characterization, and time-dependent device analysis. The project will focus on understanding how ionic motion affects device behavior and how different operating conditions can be used to tailor dynamic responses in perovskite systems. Particular attention will be devoted to identifying relationships between material properties, device architecture, and ionic transport dynamics.

You will work within a multidisciplinary team consisting of PhD students, postdoctoral researchers, senior researchers, and professors active in the fields of optoelectronics, semiconductor devices, and advanced materials. The project provides an excellent opportunity to acquire practical cleanroom experience, develop advanced experimental skills, and gain exposure to cutting-edge research conducted in an international research environment. The student is expected to be self-motivated, eager to learn new experimental techniques, and comfortable working in a collaborative research environment. A background in semiconductor devices, electronics, materials science, physics, or photonics is advantageous.
