Interstitial Hydrogen in Fe/V Superstructures: Lattice Site Location and Thermal Vibration
نویسندگان
چکیده
We report real space location of hydrogen in single crystalline $\mathrm{Fe}/\mathrm{V}$ superstructures. Anisotropic strain is quantified versus concentration by using the yield backscattered primary 2 MeV $^{4}\mathrm{H}\mathrm{e}$ ions for incidence different crystallographic directions. From a comparison ion channeling combination with $^{1}\mathrm{H}(^{15}\mathrm{N},\ensuremath{\alpha}\ensuremath{\gamma})^{12}\mathrm{C}$ nuclear reaction analysis and Monte Carlo simulations we show that located octahedral $z$ sites quantify its vibrational amplitude 0.2 \AA{}.

ANNEALING BEHAVIOR AND LATTICE SITE LOCATION OF Er IMPLANTED InGaN
Single crystalline InGaN epilayers with different In content were implanted with Er fluences in the range of 1×10 to 5×10 cm at room temperature. The structural changes and lattice site location were studied with emission channeling and RBS/channeling. Photoluminescence measurements were also performed to study the optical properties of the implanted samples. After implantation of 1×10 Er cm, t...
متن کاملEvaluation of Temperature Rise and Thermal Lesion Dimensions in Liver Laser Interstitial Thermotherapy
Introduction: Laser interstitial thermotherapy (LITT) is an internal ablation therapy method consisting of a percutaneous or intraoperative insertion of laser fibers directly into the liver tumor with maximum diameter of 5 cm. In this treatment method, there isn’t any general information about the relationship between increasing the exposure power, coagulation and carboniza...
متن کاملLearning Location from Vibration
Identifying the “semantic” location of a phone — for example, determining if it is resting on a desk, in a pocket, or on a chair — is a growing area of interest as smartphones become more prevalent. Taking advantage of the accelerometers and vibrators common in these devices, we use a machine learning approach to classify semantic location of a phone, even when it is at rest on a solid surface....
متن کاملThermal decomposition of the non-interstitial hydrides for the storage and production of hydrogen.
Hydrogen is nature’s simplest, lightest atom, consisting of a single proton and a single electron.2 Paradoxically, this “simplicity” in electronic structure leads to unique consequences for the chemical and physical properties of the element and its atomic, cationic, and anionic siblings. In its desire to possess either a totally empty or a totally filled 1s electron shell, hydrogen exhibits th...
متن کاملFundamental vibration of molecular hydrogen.
The fundamental ground tone vibration of H(2), HD, and D(2) is determined to an accuracy of 2×10(-4) cm(-1) from Doppler-free laser spectroscopy in the collisionless environment of a molecular beam. This rotationless vibrational splitting is derived from the combination difference between electronic excitation from the X(1)Σ(g)(+), v=0, and v=1 levels to a common EF(1)Σ(g)(+), v=0 level. Agreem...
