6. Quantum Materials Probed by Light and Electron Spectroscopy
Abstract : As new technologies rely heavily on materials’ properties, the quest for novel tunable electronic and magnetic materials occupies a large part of nowadays research efforts. Most promising materials are quantum materials, which exhibit a wide range of exotic electronic and magnetic phenomena and often show a great sensitivity to external perturbations such as temperature, pressure or chemical doping.

7. Angle-resolved photoemission study of unconventional cuprate superconductors
Abstract : Understanding unconventional superconductivity remains one of the most important unsolved problems in physics. A particularly noteworthy case is the copper-based high-temperature superconductor, which stands out due to its remarkably high transition temperature and relatively simple structure. READ MORE

8. Atomic and Electronic Structure of III-V Semiconductor Surfaces
Abstract : The atomic and electronic structure of clean and Cs-perturbed III-V semiconductors was studied by angle-resolved photoelectron spectroscopy (ARPES), surface core level spectroscopy (SCLS), and scanning tunneling microscopy (STM). The work can be divided into three parts, dealing with low-index sur-faces, high-index surfaces, and special features of InAs. READ MORE
