“Vacuum and Surface Science” is an academic journal published by The Japan Society of Vacuum and Surface Science. The first issue was published in January, 2018. The predecessor journals are “Journal of the Vacuum Society of Japan (JVSJ)” and “Hyomen Kagaku (Journal of the Surface Science Society of Japan)”. The journal is aiming to expand into new fields while following the article types published in the predecessors. The journal starts from Vol. 61, taking over the volume number of the long history of JVSJ.

Kyoto Collection of Human Embryo and Fetus is a valuable collection for human developmental research during pregnancy. Although serial sections contain huge morphological information, specimens are sliced and destroyed. Three-dimensional imaging in non-destructive way are developed and now applied to the human specimens. Now, morphological changes of embryo and fetus are analyzed by geometric morphometrics as well as conservative morphometric technique using obtained images.
Development of efficient fuel cell and electrochemical cell devices to retrieve energy in a renewable manner lies in the molecular level understanding of the catalytic chemical transformation processes at surfaces and interfaces. This article demonstrates the use of operando soft x-ray photoelectron spectroscopy to correlate the chemical state of electrode and the electrochemical performance of electrochemical devices. Examples are shown for oxygen reduction reaction on the Pt cathode catalyst in proton exchange membrane fuel cells, and oxygen evolution on the IrO2 anode in water electrolyzer.
Semiconductor devices with complicated structures have been developed, and it is becoming increasingly important to understand three-dimensional (3D) structures of devices with nanometer resolution. The key to successful nanometer-scale 3D analysis is sample preparation technology and it has been highly developed. By combining or correlating multiple physical analyses, limitations of single analysis method are well covered and new information of 3D devices is obtained. Simultaneously acquired multi-signal STEM images are effective for internal structure analysis of 3D devices.
We present an overview of recent studies on the moiré superlattices in Van der Waals atomic layer materials. We first introduce typical moiré superlattices such as twisted bilayer graphene and graphene h-BN superlattice. We also argue about the Hofstadter fractal energy spectrum in magnetic fields, the strain effect and domain formation, and the graphene quasicrystals.
Frequency modulation atomic force microscopy (FM-AFM) can simultaneously detect the conservative and non-conservative force interactions between a tip and a sample, based on the resonance frequency shift (Δf) and the mechanical energy dissipation of an oscillating cantilever, respectively. Here, we outline the energy dissipation measured by FM-AFM and introduce our recent results obtained through measurement of the energy dissipation. First, surface resistances can be evaluated in non-contact using the proportional relationship between the energy dissipation due to Joule heat and Δf due to the electrostatic attractive force. Second, Si adatoms on a Si(111)-(7×7) surface, which are observed to be static by FM-AFM, can move back and force between their stable sites and their neighboring quasi-stable sites, detected by measuring of the energy dissipation.
