Yáng, Z. (author), Harvey, A.S. (author), Infortuna, A. (author), Schoonman, J. (author), Gauckler, L.J. (author)Bulk BaxSr1 - xCoyFe1 - yO3 - dBaxSr1?xCoyFe1?yO3? compositions (BSCF) were synthesized by the solid-state reaction method. The electrical conductivity of ceramic bars was measured using a dc four-probe method as a function of temperature in air up to 970 °C. All compositions showed thermally activated p-type semi-conductivity up to ~450 °C and...journal article 2010

Aravind, P.V. (author), Ouweltjes, J.P. (author), Schoonman, J. (author)Electrochemical impedance measurements were carried out on symmetrical nickel/gadolinia-doped ceria test cells. For H2, N2, and H2O mixtures, the diffusion length obtained based on the impedance measurements is on the order of centimeters. This high value of the diffusion length is attributed to the flow field in the reactor. It is suggested...journal article 2009

Loef, R. (author), Schoonman, J. (author), Goossens, A. (author)Type transformation in CuInSe2 and CuInS2 solar cells is an important issue with far reaching consequences. In the present study, the presence of a p-n homojunction inside CuInS2 in a TiO2/CuInS2 device is revealed with a detailed impedance spectroscopy and capacitance study. A n-type CuInS2 film with a thickness of 40?nm is found at the TiO2 (n...journal article 2007
