A general characterization method for nonlinearities in superconducting circuits
New Journal of Physics, 2019 Detailed knowledge of nonlinearity in superconducting microwave circuits is required for the optimal control of their quantum state. We present a general method to precisely characterize this nonlinearity to very high order.

High-Velocity Shear and Soft Friction at the Nanometer Scale
Frontiers in Mechanical Engineering, 2021 We study high-speed friction on soft polymer materials by measuring the amplitude dependence of cyclic lateral forces on the atomic force microscope (AFM) tip as it slides on the surface with fixed contact force.

Zeitschrift für Physikalische Chemie, 2000 We report on the fabrication of periodic nanostructures on selected materials by short-pulse uv-laser ablation. Temporal studies reveal details of the ablation process with sub-picosecond time resolution. Biochemical applications of the nanostructures for planar waveguide technology are presented.

Telluriding monolayer MoS2 and WS2 via alkali metal scooter
Nature Communications, 2017 Two dimensional monolayer transition metal ditellurides and their alloys are interesting but their growth has been difficult. Herein, Yun et al. demonstrate the use of sodium salts to convert transition metal disulfide to ditelluride and alloys in ...

3D Micro/Nanopatterning of a Vinylferrocene Copolymer
Molecules, 2020 In nanoimprint lithography (NIL), a pattern is created by mechanical deformation of an imprint resist via embossing with a stamp, where the adhesion behavior during the filling of the imprint stamp and its subsequent detachment may impose some practical ...

Imaging high-speed friction at the nanometer scale
Nature Communications, 2016 It has been a challenge to characterize microscopic origins of friction at high velocities. Here authors extend atomic force microscopy to develop a dynamic technique combining force sensitivity and spatial resolution and able to probe, at each image ...
