1.	Lindgren, Stig-Åke, 1950, et al. (författare) Coverage-dependent frequency for Li-atom vibrations on Cu(111) 1996 Ingår i: Physical Review B. - 2469-9969 .- 2469-9950. ; 54:15, s. 10912 - 10916 Tidskriftsartikel (refereegranskat)abstract Electron-energy-loss spectra recorded for monolayer amounts of Li adsorbed on Cu(111) show a loss peak associated with Li vibrations perpendicular to the substrate. The loss energy shifts from 38 meV at low coverage to 43 meV at 0.3 ML and remains constant for coverages between 0.3 and 0.5 ML. The loss intensity passes a maximum at a Li coverage of 0.15 ML and gradually decreases such that it is difficult to resolve a loss peak at coverages above 0.5 ML. The high loss energy indicates that the adatom resides on the surfaces rather than in substitutional sites. The frequency shift is much too large to be explained by dipole-dipole interactions. The above results are obtained with the evaporation source loaded with the natural Li isotope mixture (92.6% 7Li, 7.4% 6Li). Measurements with 6Li show that the increase of the vibration frequency with increasing coverage is not an isotope effect.

8.	Carlsson, Anna K, 1966, et al. (författare) Shifts and widths of metal-overlayer quantum-well states near EF observed by photoemission 1994 Ingår i: Physical Review B - Condensed Matter and Materials Physics. - 2469-9950 .- 2469-9969. ; 50:12, s. 8926 - 8929 Tidskriftsartikel (refereegranskat)abstract Photoelectron energy spectra reveal discrete valence-electron states in the range 0–220 meV above EF for 1–3 atomic layers of Na on Cu(111). Apart from a stepwise dependence on the number of atomic Na layers the energy of the quantum-well states depends in a gradual manner on how full the layer is. The states are as well defined in energy as comparable surface states producing peak widths (50–90 meV), which depend on temperature and coverage.
9.	Duppils, Mattias, et al. (författare) A novel mixed analog/digital MAC unit implemented with SC technique suitable for fully programmable narrow-band FIR filter applications 1999 Ingår i: Proceedings of ICECS '99. The 6th IEEE International Conference on Electronics, Circuits and Systems, 1999. - 0780356829 ; , s. 1197-1200 Konferensbidrag (refereegranskat)abstract A mixed analog/digital (MAD) multiply-accumulate (MAC) unit, implemented with switched-capacitor (SC) technique is presented. The MAC unit consist of a programmable capacitor array (PCA) for coefficient representation, and an integrator for accumulation. A coefficient compensation technique to neutralize the non-ideal MAC properties due to finite opamp gain is introduced. The MAD-MAC unit is a new concept for effective mapping of signal processing tasks on SC technique; in particular high-order fully programmable narrow-band FIR filter applications. The utilization of the MAD-MAC unit concept is shown with a simulation of a decimated 400-tap narrow-band FIR filter
10.	Duppils, Mattias, et al. (författare) A study of the non-ideal properties of sample-and-hold circuits with respect to the analog bandwidth 1999 Ingår i: Proc. of 3rd IEE Int. Conf. on Advanced A/D and D/A Conversion Techniques and Their Applications. - : IEE. - 0852967187 ; , s. 119-121 Konferensbidrag (refereegranskat)abstract The fast evolving communication market demands decreased fabrication cost, which will be met by highly integrated circuit solutions. In the near future, we will see system-on-a-chip solutions in CMOS technology, where transceivers will be integrated on a single chip preferably, also with digital circuitry. Receiver topologies with A/D conversion at higher frequencies are interesting from an integration point of view. Therefore, a deeper understanding of the A/D converter limitations to cope with high-frequency signals is needed. This paper will highlight the track-and-hold circuit linearity, which is a frequency dependent fundamental limit on the A/D conversion accuracy
