Tritium concentration in tungsten surface exposed to low-energy, high-flux D plasma

K. Isobe、V. Kh. Alimov、T. Yamanishi 等 4 位作者2011-01-01OpenAlex

The limits on tritium inventory in the vacuum vessel and the need for prevention of impurity ingress into plasma make plasma-surface interaction on tungsten an important issue. It is well known that plasma exposure on tungsten makes some kinds of blisters on the surface and increases the hydrogen inventory. On the oth…

Photonic Crystal Slabs for Resonant Photodetection in Quantum Wells

S. Kalchmair、Roman Gansch、Garrett D. Cole 等 8 位作者2011-01-01OpenAlex

We present a photonic crystal slab (PCS) photodetector, designed for resonant absorption of infrared light in quantum wells. With the PCS it is possible to enhance the absorption efficiency by increasing photon lifetime in the detector active region. To design the optical properties of the device we simulate the PCS p…

Approach to calculation of long-range Coulomb interaction matrix elements in ion crystals

O. A. Anikeenok2011-01-01OpenAlex

Expressions for the calculation of matrix elements of the Coulomb interaction of the electron with an infinite crystal lattice in ion crystals have been obtained. In the general case, matrix elements are calculated on the orbitals belonging to ions of different sites. Gaussian-type orbitals are used in the calculation…

EFFECTS OF ALUMINUM ON THE PRECIPITATION RATE OF SILICA MINERALS

Hanae Saishu、Atsushi Okamoto、Noriyoshi Tsuchiya2011-01-01OpenAlex

The occurrences of silica deposits (quartz veins, silica sinters, silica scales) suggest that precipitation via nucleation and overgrowth on pre-existing mineral surfaces occurs under crustal conditions. We conducted hydrothermal flow-through experiments on silica precipitation using no mineral substrate at 120–430 °C…
