Positron annihilation spectroscopy is particularly suitable for studying vacancy-type
defects<? format?> in semiconductors. Combining state-of-the-art experimental and …

Positron is the only probe that can detect individual atomic vacancies and small and large
vacancy clusters induced by irradiation with remarkable sensitivity, providing information …

In this short topical review, a brief account of the evolution of defects due to controlled
changes in polycrystalline zinc oxide has been presented. X-ray diffraction, Positron …

Resonant positron annihilation on atomic electrons provides a powerful method to search for
light new particles coupled to e+ e-. Reliable estimates of production rates require a detailed …

Native point defects control many aspects of semiconductor behavior. Such defects can be
electrically charged, both in the bulk and on the surface. This charging can affect numerous …

Positrons beam dump experiments have unique features to search for very narrow
resonances coupled superweakly to e+ e-pairs. Due to the continued loss of energy from …

Doppler-broadening measurements of the electron–positron annihilation line in twenty-
seven single-element samples are presented. A coincidence technique has been used to …

Tungsten is considered to be used in the future fusion reactors as plasma-facing material. In
such extreme environments, defects are induced in materials that modify their macroscopic …

Meticulous surface engineering of layered structures toward new functionalities is a
demanding challenge to the scientific community. Here, we introduce defects on varied …

A bstract The inclusion of an additional U (1) gauge L μ− L τ symmetry would release the
tension between the measured and the predicted value of the anomalous muon magnetic …
