A tunneling current measurement scheme to observe Majorana-zero-mode-induced crossed Andreev reflection

New Journal of Physics, 2019
We propose a scheme to observe the Majorana-zero-mode-induced crossed Andreev reflection by measuring tunneling current directly. In this scheme a metallic ring structure is utilized to separate electron and hole signals.

Crossover from diffusive to ballistic transport in semiconductor nanostructures [PDF]

arXiv, 2005
We present a detailed microscopic study of quasi-ballistic transport in deep submicron semiconductor channels. In particular, we study the crossover between the diffusive and ballistic regimes of transport and identify signatures in the electrostatic response, electron density, and nonequilibrium electron distribution function that are due to ballistic

Negative differential conductance in the electron-transport through copper-rich cuprous oxide thin films

New Journal of Physics, 2019
Copper deposition onto Cu _2 O thin films grown on Au(111) results in the formation of monolayer islands with hexagonal and rhombic shapes, as observed with scanning tunnelling microscopy.

Improving VMAT dose calculation accuracy and planning quality via a GPU‐accelerated Fourier transform dose calculation algorithm

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background Inverse planning typically utilizes fast, less accurate dose calculation algorithms during the iterative optimization process, thus leading to dose calculation errors (DCEs) and suboptimal plans that often require dose normalization and/or plan re‐optimization.

Diagnosis of Weibel instability evolution in the rear surface density scale lengths of laser solid interactions via proton acceleration

New Journal of Physics, 2017
It is shown for the first time that the spatial and temporal distribution of laser accelerated protons can be used as a diagnostic of Weibel instability presence and evolution in the rear surface scale lengths of a solid density target.

Coupled electron-phonon hydrodynamics in two-dimensional semiconductors [PDF]

arXiv
Electronic and thermal transport properties in two-dimensional (2D) semiconductors have been extensively investigated due to their potential to miniaturize transistors. Microscopically, electron-phonon interactions are considered the dominant momentum relaxation mechanism for electrons that limits carrier mobility beyond cryogenic temperatures. However,

High spatial resolution dosimetry for radiation oncology with “MagicPlates,” a new 976‐pixel monolithic silicon detector

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose We introduce the next generation of “MagicPlate” 2D monolithic pixelated semiconductor detectors – MagicPlate‐976 (MP976). It features a larger array area, higher spatial resolution, and does not require external triggering. We perform a comprehensive characterization for small‐field steep‐dose‐gradient dosimetry applications in ...

Does dose calculation algorithm affect the dosimetric accuracy of synthetic CT for MR‐only radiotherapy planning in brain tumors?

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose This study compares the dosimetric accuracy of deep‐learning‐based MR synthetic CT (sCT) in brain radiotherapy between the Analytical Anisotropic Algorithm (AAA) and AcurosXB (AXB). Additionally, it proposes a novel metric to predict the dosimetric accuracy of sCT for individual post‐surgical brain cases.
