Disentangling lattice and electronic contributions to the metal–insulator transition from bulk vs. layer confined RNiO₃

, 2019
In complex oxide materials, changes in electronic properties are often associated with changes in crystal structure, raising the question of the relative roles of the electronic and lattice effects in driving the metal–insulator transition.

A performance comparison between GaInP-on-Si and GaAs-on-Si 3-terminal tandem solar cells

iScience, 2022
Summary: The pursuit of ever-higher solar cell efficiencies has focused heavily on multijunction technologies. In tandem cells, subcells are typically either contacted via two terminals (2T) or four terminals (4T).

Proximity Scanning Transmission Electron Microscopy/Spectroscopy [PDF]

arXiv, 2016
Here a new microscopic method is proposed to image and characterize very thin samples like few-layer materials, organic molecules, and nanostructures with nanometer or sub-nanometer resolution using electron beams of energies lower than 20 eV. The microscopic technique achieves high resolution through the proximity (or near-field) effect, as in ...

In vivo transit dosimetry methodology for whole breast intensity modulated radiation therapy

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background In vivo transit dosimetry using an electronic portal imaging device (EPID‐IVTD) is an important tool for verifying the accuracy of radiation therapy treatments. Despite its potential, the implementation of EPID‐IVTD in breast intensity modulated radiation therapy (IMRT) treatments has not yet been standardized, limiting its clinical

A multimode photodetector with polarization-dependent near-infrared responsivity using the tunable split-dual gates control

iScience, 2022
Summary: As the limited carrier densities in atomic thin materials can be well controlled by electrostatic gates, p-n junctions based on two-dimensional materials in the coplanar split-gate configuration can work as photodetectors or light-emitting ...
