Moreover, you are part of designing the future of synchrotron technology and instrumentation and using these to tackle some of the most significant global challenges the world faces today while acquiring interdisciplinary and intersectoral knowledge. Being part of the PRISMAS programme gives you a one-of-a-kind experience in the form of a secondment at the world´s first 4th generation synchrotron, MAX IV in Lund, Sweden. With a tailored training programme, including courses to build scientific and technical competence as well as strengthen transferrable skills, PRISMAS provides you with the skills, knowledge and competence needed to successfully achieve your doctoral degree.

The MSCA COFUND project PRISMAS offers you outstanding opportunities as well as a stimulating and inspiring surrounding for performing cutting-edge research. By supporting your mobility, it creates perfect conditions for strengthening your international network.

The research conducted at the Department of Physics and Astronomy encompasses a wide range of physics topics, distributed over nine divisions. The department is located in the Ångström laboratory and employs nearly 400 people, 100 of whom are doctoral students. It offers a broad physics curriculum to undergraduate and graduate students, participation in nationally and internationally leading projects for researchers, and opportunities for partnership with industry and various outreach activities. Here, the program Condensed Matter Physics of Energy Materials research aims to develop an understanding of electronic properties at the atomic level and new functional materials for energy and environmental applications.

The Quantum Material Device group at Uppsala University is funded by the European Research Council (ERC) and the Knut and Alice Wallenberg (KAW) Foundation to push the boundaries of quantum materials research. The group's overarching research focuses on developing innovative quantum material devices, investigating charge, spin, and orbital quantum phenomena, and exploring their potential for various applications such as energy-efficient memory and logic devices, flexible spintronic devices, novel quantum sensors, and intelligent spin-integrated and neuromorphic circuits. The group employs two-dimensional (2D) crystals such as graphene, 2D semiconductors such as dichalcogenides MoS2 and MoSe2, 2D insulators like hexagonal boron nitride, and special laminates and precisely angle-oriented 2D van der Waal heterostructures. Experiments involve comprehensive low-temperature (down to 10 millikelvins) charge, spin (orbital) transport, and magneto-optics to uncover novel ordering, exotic charge and spin phenomena, and emergent physics. These experiments are enabled by developing custom-built in-house instrumentation and precision measurement techniques. In addition, the novel materials are also explored by advanced X-ray spectroscopic techniques.

He is an expert in quantum material device physics of nanoelectronics and spintronic devices, innovative device fabrication, synthesis of 2D materials, and instrumentation and precision charge, spin, and orbital measurements. He was awarded an ERC-consolidator grant in 2020 and leads the Quantum material device group (host group) with 4 Ph.D. students and 4 Postdocs.

Co-PI Dr. Zhaojun Li is known for her internationally recognized work on functionalized 2D material for optoelectronics. Co-PI Assoc. Prof. Andreas Lindblad is an expert on charge dynamics study with electronic structures probed by X-rays. He specializes in nanometric profiling of the elemental and chemical specificity of the novel hetero-layers we will produce in this project. Co-PI Dr. Anirudha Ghosh is an expert in the field of soft x-ray spectroscopy. He is currently stationed at Veritas beamline in MAX IV Laboratory, and specializes in understanding the charge and spin dynamics of correlated electron systems, 2D van der Waal materials, superconductors, etc. The secondments at MAX IV Laboratory will be under his supervision.

Duties
Two-dimensional (2D) material van der Waals (vdW) heterostructures exhibit extraordinary quantum traits for next-generation nanoelectronics, spintronics, and optoelectronic applications. The project aims to investigate the quantum (electronic, phononic, and magnonic) properties and phenomena in novel directly-chemical vapor deposited 2D material heterostructures and their functionalized defect-passivated systems, and develop innovative devices. Here we will explore a new direct growth of 2D material heterostructures, for example, semiconducting MoS2 on graphene. Recently, we have innovated the growth of composite 2D heterostructures by nucleation-defined chemical vapor deposition. In this project, we specifically aim to probe the electronic structure of these new quantum materials via advanced x-rays spectroscopic tools, such as angle-resolved photoemission (ARPES), resonant inelastic x-ray scattering (RIXS), ambient pressure x-ray photoemission spectroscopy (APXPS), nano and micro-(ARPES), to uncover the band structure and surface charge transfer in directly CVD-grown 2D heterostructures of MoS2 over graphene and 2D magnets (Chromium Telluride) over graphene. This will help in understanding spin-orbit coupling and its influence on the electronic and magnonic (involving magnetic 2D materials) band structure in 2D heterostructures. In addition, the project will involve the investigation of defect passivation by chemical treatments on CVD-grown 2D materials. These objectives will impact the understanding of the properties of the directly grown 2D heterostructures and engineering their properties for efficient next-generation optoelectronic and spintronics devices, which will be innovated with these quantum materials. This project is expected to significantly contribute to pushing the boundaries of 2D quantum materials.

The focus of the project will be to synthesize innovative two-dimensional (2D) material heterostructures and characterize them using advanced transport, magneto-optic, and x-ray spectroscopic techniques. The student will be part of exciting developments at Uppsala University in 2D material research and get an exciting opportunity to learn, employ, and innovate the growth of 2D materials by chemical vapor deposition techniques, and various in-house measurement and characterization techniques at the Quantum Material Device laboratory. In addition to growth, this project would involve significant utilization of X-ray spectroscopic techniques to uncover the band structure of the novel 2D heterostructures, 2D passivated materials, finding intricate details using advanced spectroscopic techniques in achieving the project objectives.

The training implies a secondment of 3-12 months at MAX IV laboratory in Lund, Sweden. Additional secondments and/or short stays may be arranged in agreement with the supervisor of the research project. Moreover, you will attend international conferences, participate in periodical project meetings and training schools as well as in specialised courses at different universities to complement your knowledge.  A certain amount of travelling is foreseen in relation to these activities.
