Ultrafast thermal boundary conductance under large temperature discontinuities of ultrathin epitaxial Pb films on Si(111)
Christian Brand, Tobias Witte, Mohammad Tajik +5
Heat transfer is a critical aspect of modern electronics, and a deeper understanding of the underlying physics is essential for building faster, smaller, and more powerful devices…
Implementation and performance of a fiber-coupled CMOS camera in an ultrafast reflective high-energy electron diffraction experiment
Jonas D. Fortmann, Alexander Kaßen, Christian Brand +2
The implementation of a monolithic fiber-optically coupled CMOS-based TemCam-XF416 camera into our ultra-high vacuum (UHV) ultrafast reflection high-energy electron diffraction set…
Cool Cooling Collar for Bake-Out of Temperature-Sensitive Devices
Jonas D. Fortmann, Christian Brand, Michael Horn-von Hoegen
A combination of a pumpable gate valve and a self-built cooling collar permits bake-out of an ultra-high vacuum chamber without having to dismount sensitive equipment. A small pump…
Non-Equilibrium Pathways for Excitation of Bulk and Surface Phonons through Anharmonic Coupling
C. Brand, V. Tinnemann, A. Hanisch-Blicharski +5
Upon impulsive optical excitation of solid-state materials, the non-equilibrium flow of energy from the excited electronic system to the lattice degrees of freedom typically happen…
Critical behavior of the dimerized Si(001) surface: Continuous order-disorder phase transition in the two-dimensional Ising universality class
Christian Brand, Alfred Hucht, Hamid Mehdipour +8
The critical behavior of the order-disorder phase transition in the buckled dimer structure of the Si(001) surface is investigated both theoretically by means of first-principles c…
Dimer Coupling Energies of the Si(001) Surface
Christian Brand, Alfred Hucht, Giriraj Jnawali +6
The coupling energies between the buckled dimers of the Si(001) surface were determined through analysis of the anisotropic critical behavior of its order-disorder phase transition…
