Abstract Superconductivity of iron chalocogenides is strongly enhanced under applied pressure yet its underlying pairing mechanism remains elusive. Here, we present a quantum oscillations study up to 45 T in the high-T c phase of tetragonal FeSe0.82S

Left ventricular diverticulum (LVD) is a rare malformation presenting in 0.05% of all congenital cardiac anomalies. It is associated with additional cardiac and extracardiac malformations. We report on a female neonate with prenatally diagnosed heter

This paper proposes to extract the generation and recombination lifetime simultaneously from the recombination current in forward operation. The method is applied to n + –p-well junctions fabricated in advanced processing schemes on silicon wafers

A nitrogen-doped floating zone (FZ) crystal with a linear increase of the axial nitrogen content from zero to more than 1×10 15 at/cm 3 was grown. It was found that the defect-free zone increases with increasing nitrogen content, until it extends ov

In the present stage of development, 300 mm crystals often contain a transition from vacancy-rich to interstitial-rich. Due to this radially varying concentration of intrinsic point defects, the radial size distribution of grown-in oxide precipitate

Two superconducting microwave billiards have been electromagnetically coupled in a variable way. The spectrum of the entire system has been measured and the spectral statistics analyzed as a function of the coupling strength. It is shown that the res

Density spectra of grown-in oxide precipitate nuclei were measured along the radius of a silicon wafer with a stacking fault ring. A first-order approximation model allows us to explain the experimental observations. By fitting growth rate curves to
