"To blog or not to blog?" Finally, at the biblical age of 70, I decided to have a crack at it. It starts formally, with increasing cover of some personal matters. I minimize comments on science - covered elsewhere (more news here later). A few considerations though where science and society collide. Comments, contributions, suggestions and new contacts are welcome on: . subsequently ionize gas molecules by collision. These ions bombard and sputter the titanium cathode. The sputtered titanium then getters any active gases. Heavy noble gases are typically pumped by ion burial into the plate. Description of the operation of a getter ion pump may be found elsewhere [,]. The ultimate pressure of the system.

Sputtering of solid Ne with the hydrogen ions H + 1, H + 2 and H + 3 in the energy range 1–10 keV/atom has been studied by means of a quartz microbalance technique.
No enhancement in the yield per atom for molecular ions was found. The results for hydrogen ions are compared with data for keV by: Nuclear Instruments and Methods in Physics Research B18 () North-Holland, Amsterdam Section VIIL Sputtering of condensed gases ELECTRONIC SPUTI'ERING OF SOLID ARGON AND KRYPTON BY keV HYDROGEN IONS J.

Most sputtering is done by energetic sulfur ions (s of keV to MeV), but most of the O2 and H2 production is done by cold oxygen ions (temperature ˜ eV, total energy ˜ eV). Abstract. A number of common features for the erosion of condensed gases by ion or electron bombardment are discussed.
The overall pattern shows many similarities for erosion via electronic transitions induced by primary electrons and light by: 2. The sputtering yield induced by keV hydrogen ions measured at CERN and at Risø National Laboratory for solid H2 and D2 at temperatures below K decreases with increasing film thickness from.

The radiolysis of solid D-valine (–2 μm thick) was performed at room temperature by MeV H+, He+, N+, and MeV S15+ ion beams. The samples were prepared by spraying/dropping valine-water-ethanol solution on ZnSe substrate.
Radiolysis was monitored by infrared spectroscopy (FTIR) through Author: Cíntia A. da Costa, Gabriel S. Vignoli Muniz, Philippe Boduch, Hermann Rothard, Enio F. da Silvei. The electron is a subatomic particle with a negative charge, equal to x t, or the rate of flow of charge, is defined such that one coulomb, so 1/x, or x10 18 electrons flowing past a point per second give a current of one charge on an electron is often given as -e.

How did life begin on Earth. And is there life elsewhere in the Cosmos. Challenging questions, indeed. The series of conferences established by NoR CEL inaddresses these very same questions. The basis for this paper is the summary report of oral presentations that were delivered by NoR CEL’s network members during the Athens conference and, as such, disseminates the latest Cited by: 1.

Chapter 1 Basic Semiconductor Physics and Technology 44 Silicon nitride can be deposited using plasma-enhanced chemical vapour deposition (PECVD) or low-pressure chemical vapour deposition (LPCVD), using silane and ammonia gases NH 3, although the former is the technique of choice for glassivation purposes because it allows a lower processing.
The UNT Digital Library is a centralized repository for the rich collections held by the libraries, colleges, schools, and departments at the University of North Texas. In this study, we have fabricated nanofuses from thin-film, arc-deposited carbon for use in permanent data storage.
Thin-film carbon fuses have fewer fabrication barriers and retain the required resistivity and structural stability to act as a data-storage medium. Carbon thin films were characterized for their electrical, microstructural, and chemical bonding by: 1. The energy of the ions were varied from 50 keV to 80 keV to obtain the distribution of implanted ions in the silicon nanowire.
The simulation were also carried out using different straggling models. The presence of Fe and Co ions are expected to facilitate the formation of. Therefore we look at the energy dissipated by both 30 keV electrons and ions in a silicon substrate. For simulating the eﬀect of energetic ions on matter a program called 2 For example for platinum, IBID and EBID as deposited purities are around.
