Gallium ion FIB-SEM sample preparation has a damage limit; low-energy argon ion beam cleaning is used to improve TEM sample quality

Gallium ion focused ion beam-scanning electron microscopy (Ga⁺ FIB-SEM) has become an important method for site-specific thin lamella sample preparation for transmission electron microscopy/scanning transmission electron microscopy (TEM/STEM), enabling cutting, extraction, and thinning of target regions at the nanometer scale. However, the literature indicates that while gallium ions provide high-precision machining capability, they also cause amorphization, ion implantation, and localized chemical modification on the sample surface, which can subsequently affect high-resolution imaging and energy dispersive spectroscopy analysis results. According to the literature, Ga⁺ FIB-SEM typically enables high-resolution site-specific machining at 30 keV, but high-energy gallium ions form a damage layer on the sample sidewalls. Taking silicon as an example...

Lancaster University in the UK receives EPSRC funding to study antimatter production in intense laser pulses

Christopher Arran, a lecturer at Lancaster University and the Cockcroft Institute in the UK, has recently been awarded a three-year New Investigator Award from the UK Engineering and Physical Sciences Research Council (EPSRC) to study electron-positron pair production in the extremely intense electromagnetic fields of high-power lasers. The research focuses on matter-antimatter production processes under intense laser pulse conditions. Similar interactions are believed to exist in extreme cosmic environments, such as near pulsars and black hole accretion disks. Previously, such interactions had only been measured at large particle accelerator facilities such as Stanford University and the European Organization for Nuclear Research (CERN), but the electric and magnetic field strengths used in those experiments were far weaker than the strong-field conditions achievable with current high-power lasers.

Rare Germanium Isotope Infrared Spectral Signatures Elucidated in Detail for the First Time

The press service of the Russian Ministry of Education and Science reported on August 25 that scientists from Tomsk Polytechnic University, in collaboration with an international research team, have for the first time conducted a detailed study of the infrared spectra of two rare germanium isotopes and identified characteristic spectral signatures that can be used to recognize the relevant isotopes in complex gas mixtures. The research team selected two highly enriched isotopes—germanium-72 and germanium-73—as the subjects of the study, recording their spectral information using a high-resolution Fourier transform spectrometer. This instrument is capable of resolving closely spaced spectral lines, providing the conditions for analyzing subtle spectral changes induced by isotopic substitution. The researchers stated that precise spectral data for different germanium isotopes remain relatively scarce in the scientific literature, and such data are of significant importance for identifying molecules in planetary atmospheres and for producing ultra-pure germanium isotopes for quantum technologies and modern electronics.

Singapore team develops deuterated silicon nitride waveguides for wafer-scale broadband light generation

A research team from the Singapore University of Technology and Design and the Institute of Microelectronics at the Agency for Science, Technology and Research (A*STAR) in Singapore has recently developed a low-loss deuterated silicon nitride waveguide capable of on-chip broadband light generation. By replacing hydrogen with its heavier isotope deuterium, the team fabricated silicon nitride waveguides at low temperatures, demonstrating potential for integration with CMOS-compatible semiconductor processes and wafer-scale mass production. The related paper, "Octave-spanning supercontinuum generation in wafer-scale low-loss deuterated silicon nitride waveguides," was published in *Optics Letters*. The study shows that this chip-scale waveguide can broaden infrared laser pulses to cover a spectral range from visible red light to deep infrared. Traditionally, silicon nitride thin films are grown from silane gas, and residual silicon-hydrogen bonds in the material absorb light in the telecommunications band, requiring high-temperature annealing that is incompatible with integrated electronic circuits.
