Multi‐Slit Diffraction in Scaled Space‐Time

open access: yesNatural Sciences, EarlyView.
A space‐time scaling is used to transform quantum wave packets describing free particle motion to packets moving in an effective harmonic oscillator potential that confines and directs the wave fronts along the classical phase space of the oscillator. The transformation is applied to multi‐slit diffraction and shown to characterize diffraction features

Climatic Specific Energy Rating Analysis of Outdoor PV Field Data

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
The study evaluates the Climatic Specific Energy Rating (CSER) of Photovoltaic device according to IEC 61853 standard series. It explores the use of long‐term PV outdoor field data in order to understand how the length and seasonality of the data acquisition period affects the reliability of the CSER parameter. It provides important insights for the PV

Corrections of Electron–Phonon Coupling for Second‐Order Structural Phase Transitions

open access: yesphysica status solidi (b), EarlyView.
The left image illustrates a weak electron–phonon coupling, while the right image depicts a strong electron–phonon coupling. The weak electron–phonon coupling interaction between the lattice and electrons is susceptible to destabilization by an increase in temperature.

Fundamental Properties of Heavily Ge‐Doped AlGaN Prepared via Pulsed Sputtering

open access: yesphysica status solidi (b), EarlyView.
This study explores the properties of heavily Ge‐doped AlGaN films prepared via pulsed sputtering deposition. Films with Al content below 34% exhibit higher electron concentrations than Si‐doped counterparts. The maximum carrier concentration reaches 1.8 × 1020 cm−3. Optical bandgaps are enhanced by the Burstein–Moss shift.
