Core nucleus polarization in Λ hypernuclei
(The American Physical Society, 2008-03)
The response of the core nucleus to the Λ in a hypernucleus is studied with a local density approximation. This reproduces the energies and radii of the core nuclei as well as the Λ-single particle (s.p.) energies quite ...
A voltage reference circuit for current source of RFIC blocks
(Emerald Group Publishing Limited, 2008)
Purpose - The purpose of this paper is to design a voltage reference circuit for current source of radio frequency integrated circuit blocks. The voltage reference circuit is called voltage for current source (VCS). ...
Optical investigations using ultra-soft pseudopotential calculations of Si0.5Ge0.5 alloy
(Elsevier Ltd, 2008-12)
Ultra-soft pseudopotential (US-PP) calculations with a powerful package called VASP (Vienna ab initio simulation package) are used. The total density of state and the energy gap of Si0.5Ge0.5 alloy of zinc-blende structure ...
Fabrication and characterization of Si quantum dots and SiO2 tunnel barriers grown by a controlled oxidation process
(IOP Publishing Ltd, 2008-01-29)
The control of the growth of silicon dioxide (SiO2) and the formation of quantum dots (QDs) play an important role in the fabrication of single-electron transistors (SETs). In this work, SET structures were fabricated using ...
High-sensitivity pressure sensor using a polymer-embedded FBG
(Wiley Periodicals, Inc., 2008-01)
A new pressure sensor based on fiber Bragg gratings (FBG), is described with high-pressure sensitivity. The sensor is configured by embedding the FBG in a polymer-field aluminum casing with an opening on one side, which ...
Characterization of intermetallic growth of gold ball bonds on aluminum bond pads
(University of Malaya, 2008)
In this paper the intermetallic growth between gold ball bond and aluminum bond pad are studied. It involves thermal aging at 150 °C and 200 °C for various time intervals. The relationship between electrical resistance and ...
