Calculational aspects of electron-phonon coupling at surfaces

Tidskriftsartikel (refereegranskat)abstract
- We study the validity of two frequently used approximations in calculations of electron–phonon coupling at surfaces. The rigid-ion approximation is a standard approximation used for the bulk metals. On the basis of density functional theory calculations, we find that for Be this approximation is as valid for surface atoms as for bulk atoms. In addition, the slab method for calculations of a phonon induced surface state lifetime is examined. The convergence of the electron–phonon matrix element with respect to the thickness of the slab is studied for several systems. When the number of slab layers is increased, the net effect of decreasing overlap and increasing number of final states depends strongly on the decay length of the surface state wavefunction and the band structure.

Model Eliashberg function for surface states
- 2008
-
Ingår i: Applied Surface Science. ; 254:23
-
Tidskriftsartikel (refereegranskat)abstract
- We present a simplified procedure for the analysis of the phonon-induced lifetimes of surface states. The model includes information about the electron and phonon structure and is thus more reliable than procedures based on phonon Debye models. We apply the model to calculate the lifetime broadening of Cu(1 1 1) and Al(0 0 1) surface states. The obtained Eliashberg functions and lifetimes are in reasonable agreement with previous detailed studies.

A place to live : gender research on housing in Africa
- 1996
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Be it a house or a makeshift, a shared or rented room, or a home of one's own, a place to live is central in surviving strategies of all urban households. In this volume the authors explore the gendered experiences of housing and housing rights in African countries. There are many differences but also many similarities in the pattern of women not having the same access and control over housing as men have. While women often are the bread-winners, they are also the home-makers, in the sense that it is women who put intense efforts in making a place home.

Evaluation of an In-work Tax Credit Reform in Sweden: Effects on Labor Supply and Welfare Participation of Single Mothers
- 2008
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The purpose of this paper is to evaluate a recent Swedish in-work tax credit reform where we pay particular attention to labor market exclusion; i.e. individuals in as well as outside the labor force are included in the analysis. To highlight the importance of the joint effects from the tax and the benefit systems it appears particular relevant to analyze the labor supply behavior of single mothers. To this end, we estimate a structural microeconometric model of labor supply and welfare participation. The model accounts for heterogeneity in consumption-leisure preferences as well as for constraints in job opportunities. The results of the evaluation show that the reform generates welfare-gains for virtually every single mother, and moreover benefits low-income households. Finally, due to increased labor supply and decline in welfare participation we find that this reform is almost self-financing.
