Condensed-Matter Physics & Materials Science Seminar

"Optical Second Harmonic Generation Measurements of BaTi205 and Low-k Dielectrics"

Presented by Joanna Atkin, Columbia University

Monday, November 23, 2009, 1:30 pm — Small Seminar Room, Bldg. 510

Optical Second Harmonic Generation (SHG) is a powerful technique for probing symmetry-breaking processes in materials. Two examples, the use of SHG for investigating ferroelectricity in BaTi2O5 and the dynamics of charge carrier processes in low-k dielectric materials (LKDs) will be discussed. Measurements with electrical/optical techniques to determine the basic electronic properties of LKDs, and interpretations of these results in the context of reliability, will also be presented
