The results of deep CCD field surveys: Very low mass halo population stars as dark matter
(The American Institute of Physics, 1995-07-01)
Halo and disk M dwarfs differ significantly in metallicity. Multi‐color deep CCD surveys are uniquely capable of detecting these separate populations of stars with differing metallicity and therefore colors. Analyzing very ...
Optical properties of silicon nitride films deposited by hot filament chemical vapor deposition
(The American Institute of Physics, 1995-06-15)
Silicon nitride films were deposited at low temperatures (245–370 °C) and high deposition rates (500–1700 Å/min) by hot filament assisted chemical vapor deposition (HFCVD). Optical properties of these amorphous silicon ...
Laser cavity mirror imperfections and reflectivity: A time‐dependent numerical approach
(The American Institute of Physics, 1995-02-27)
While the cleaving process used for semiconductor Fabry–Pérot lasers produces atomically abrupt mirrors, there is considerable interest in mirrors defined by etching. Depending on the etching process employed, disorder of ...
Si nanostructures fabricated by anodic oxidation with an atomic force microscope and etching with an electron cyclotron resonance source
(The American Institute of Physics, 1995-04-03)
Nanometer‐scale Si structures have been fabricated by anodic oxidation with an atomic force microscope (AFM) and dry etching using an electron cyclotron resonance (ECR) source. The AFM is used to anodically oxidize a thin ...
A spin polarized disc
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1995-03)
We present a solution to the gravitational field equations in a Riemann-Cartan spacetime. The solution describes a disc of infinite radius and finite thickness. The solution has three forms which depend on the size of the ...
Asymptotic expansions of Witten–Reshetikhin–Turaev invariants for some simple 3‐manifolds
(The American Institute of Physics, 1995-11)
For any Lie algebra @Fg and integral level k, there is defined an invariant Zk∗(M, L) of embeddings of links L in 3‐manifolds M, known as the Witten–Reshetikhin–Turaev invariant. It is known that for links in S3, Zk∗(S3, L) ...
