The division of Condensed Matter and Materials Theory constructs models for and develops an understanding of a large variety of materials and other condensed matter systems, sometimes leading to new materials, novel technological devices, or structured media with properties beyond those occurring naturally. To this end, we combine theoretical, methodological and computational techniques, often in close collaboration with local and international experimental groups. The work in the division is characterized by a strong interplay between fundamental and applied research and this allows us to address pressing societal challenges, e.g., related to sustainable energy or information technology.
We take active part in Chalmers' undergraduate and postgraduate educational programmes. Our students gain experience in advanced theory and model-building, developing strong analytical, computational, and problem-solving skills along the way. They are exposed to collaborative efforts, often within our international research networks. Our vision is to foster the individual growth of our students, so they may in the future be insightful and effectively contribute to society, academia, and industry.
We are looking for a PhD student to work on electronic structure modeling of materials for solar devices. Searches for materials with specific properties are the bottlenecks of many emerging semiconductor technologies, such as quantum computing, electronics and solar energy conversion. Properties matching a desired function are key to the introduction of new technologies, but as development approaches final implementation, all components need to be tuned for a harmonious coexistence within a micro-device via doping, surface functionalization, nano-scale engineering, or other methods. From the point of view of first-principles modeling, a microdevice is a stack of functional layers (1, 2 or 3D, organic or inorganic), separated by interfaces - i.e. volumes within which the proximity or bonding between two neighboring materials influences the properties, and causes a deviation from the bulk state. The present project will focus on comprehensive modeling of various materials that are used in a solar cell, such as the photoabsorber (halide perovskite in particular), hole and electron transport layers, and their interfaces. Advanced electronic structure methods, hybrid functionals and ab-initio molecular dynamics simulations, as implemented in the ABINIT, QuantumEspresso or CP2K codes, will be used.
Major responsibilities
During the PhD project you will work on performing electronic structure calculations for materials used in a solar cell, such as the perovskite photoabsorber, hole and electron transport layers and their interfaces. You will investigate for instance the behavior of defects and excess charges in these material and study how their properties may change when the materials are put together in a single device. You will engage in collaborations with experimental groups. As part of the project, you will be expected to communicate research results both orally at international conferences and in writing in scientific journals.
Your major responsibilities are to pursue your own doctoral studies. You are expected to develop your own scientific concepts and communicate the results of your research verbally and in writing. The position generally also includes teaching on Chalmers' undergraduate level or performing other duties corresponding to 20 per cent of working hours.
Qualifications
You should hold a Master degree or equivalent in physics, chemistry or materials science and have a strong interest in computational modeling and electronic structure calculations. You should enjoy working in a collaborative environment including interactions with both theoreticians and experimentalists.
The position requires sound verbal and written communication skills in English. If Swedish is not your native language, Chalmers offers Swedish courses.
Contract terms
Full-time temporary employment. The position is limited to a maximum of five years.

Chalmers offers a cultivating and inspiring working environment in the coastal city of Gothenburg.
