Diffusion lengths of silicon solar cells from luminescence images (2007)
Würfel, P., Trupke, T., Puzzer, T., Schäffer, E., Warta, W., Glunz, S.W.
A method for spatially resolved measurement of the minority carrier diffusion length in silicon wafers and in silicon solar cells is introduced. The method, which is based on measuring the ratio of...

Capillary instabilities by fluctuation induced forces (2003)
Morariu, M D, Schäffer, E., Steiner, U.
The spontaneous break-up of thin films is commonly attributed to the destabilizing effect of van-der Waals forces. Dispersion forces can be considered in terms of the confinement of the...
Hock, M., Schäffer, E., Döll, W., Kleer, G.
The application of glass moulding processes to the fabrication of microoptical components is up to now limited by the problem of sticking between the aggressive glass melts and the moulding tools. In...
Kleer, G., Döll, W., Hock, M., Manns, P., Schäffer, E.
In future technologies of telecommunication and laser techniques there is a high demand on microoptical components having aspherical or fresnel- and grid-shaped surfaces. For many of these components...
Temperature-gradient-induced instability in polymer films (2002)
Schäffer, E., Harkema, S., Blossey, R., Steiner, U.
We report the experimental observation and a theoretical model for a thin-film instability caused by a temperature gradient. A polymer-air double layer sandwiched between two plates set to different...
