Based on the current state of the art Marcus Lau demonstrates an improved experimental design for defined laser irradiation of particles in liquid environment. The experimental results achieved with the designed reactor demonstrate how particle properties can be modified by defined laser energy dose input. By utilizing different model materials new insights into laser processing of particles in liquids are gained that allow an enhanced process understanding.

Denise Reichel studies the delicate subject of temperature measurement during lamp-based annealing of semiconductors, in particular during flash lamp annealing. The approach of background-correction using amplitude-modulated light to obtain the sample reflectivity is reinvented from rapid thermal annealing to apply to millisecond annealing. The author presents a new method independent of the lamp operation to obtain this amplitude modulation and derives a formula to describe the process. Further, she investigates the variables of the formula in depth to validate the method's suitability...

Christian Pauly demonstrates the strong topological properties of the technologically relevant phase change materials Sb₂Te₃ and Ge₂Sb₂Te₅ by using two powerful techniques for mapping the surface electronic structure: scanning tunneling spectroscopy (STS) and angle-resolved photoemission spectroscopy (ARPES). In the case of a phase change material, this opens up the possibility of switching between an insulating amorphous and a conducting topological phase on nanosecond-time scales. Moreover, the author presents first experimental...

Mihai Stoica investigates in details the glass formation of two model alloys, (Fe_0.5Co_0.5)_0.75B_0.2Si_0.05]₉₆Nb₄ and Fe₇₄Mo₄P₁₀C_7.5B_2.5Si₂. More than 20 master alloys using different raw materials were prepared. Besides the typical calorimetry and X-Ray diffraction, magnetic measurements were employed to analyze the amorphicity degree of the sample. Two new bulk metallic glass-forming alloy compositions are designed and possible preparation routes...
