Abstract: Due to its low beam current and charge compensation mechanism He-Ion scanning microscopy is a very promising tool for imaging biological cells. However, to obtain relevant information, the method used for s le preparation is also critical. In this work, we have used a Carl Zeiss Orion Plus helium-ion microscope to study the effect of s le gold coating on the morphology of human colorectal adenocarcinoma Caco2 cells. The fixative glutaraldehyde was used and the selective gold coating of the s les was investigated. A comparative study with standard scanning electron microscopy is presented.

Abstract: The authors present experimental results showing the effect of an applied bias voltage on backscattered ion spectra acquired from thin films of ruthenium and hafnia in the helium ion microscope. A characteristic peak associated with the presence of a thin layer of material is observed to shift as a function of s le bias voltage. The magnitude of this shift is measured, and the authors qualitatively estimate the composition of their s les as well as investigate the neutralization of ions by the s le in the helium ion micoscope (HeIM). They discuss the phenomenona in terms of thin films of ruthenium and hafnia and show the implications of these results on HeIM spectroscopy.

Abstract: Two-dimensional (2D) layered semiconductors have recently emerged as attractive building blocks for next-generation low-power nonvolatile memories. However, challenges remain in the controllable fabrication of bipolar resistive switching circuit components from these materials. Here, the experimental realization of lateral memtransistors from monolayer single-crystal molybdenum disulfide (MoS
