Surface Reordering During Layer‐by‐Layer Growth on SrTiO3

Advanced Materials, EarlyView.
Surface structures (left) derived from DFT‐constrained fitting to crystal truncation rods measured by synchrotron X‐ray scattering (right) after each monolayer of deposition during the MBE growth of SrTiO3${\rm SrTiO}_{3}$ (001). The bottom panel shows the bare substrate, the middle panel shows island formation upon deposition of a single layer of SrO,

Tensor characteristics of forward Brillouin sensors in bare and coated fibers

APL Photonics, 2023
Forward Brillouin scattering fiber sensors can detect and analyze media outside the cladding of standard fibers, where guided light does not reach. Nearly all such sensors reported to-date have relied on the radially symmetric guided acoustic modes of ...

Multi-band spectroscopy of inhomogeneous Mott-insulator states of ultracold bosons

, 2009
In this work, we use inelastic scattering of light to study the response of inhomogeneous Mott-insulator gases to external excitations. The experimental setup and procedure to probe the atomic Mott states are presented in detail.

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

Advanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Microwave Absorption for Detection of Dirac Fermions in SnTe Films

Advanced Materials Interfaces, EarlyView.
Microwave absorption can detect Dirac fermions in samples exposed to the atmosphere. Results showed that although topological surface states are robust against environmental degradation, they are not detectable by electrical transport measurements. Hence, microwave absorption can detect Dirac fermions even in samples whose surfaces have deteriorated ...

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...
