Domain wall motion in epitaxial Pb(Zr,Ti)O3 capacitors investigated by modified piezoresponse force microscopy
S. M. Yang, J. Y. Jo, D. J. Kim +5
We investigated the time-dependent domain wall motion of epitaxial PbZr0.2Ti0.8O3 capacitors 100 nm-thick using modified piezoresponse force microscopy (PFM). We obtained successiv…
Optical Study of the Free Carrier Response of LaTiO3/SrTiO3 Superlattices
S. S. A. Seo, W. S. Choi, H. N. Lee +4
We used infrared spectroscopic ellipsometry to investigate the electronic properties of LaTiO3/SrTiO3 superlattices (SLs). Our results indicated that, independent of the SL periodi…
Effects of the Two- Gap Nature on the Microwave Conductivity of 39 K Polycrystalline MgB2 Films
Sang Young Lee, J. H. Lee, Jung Hoon Han +4
The surface resistance (Rs) and the real part (sigma_1) of the microwave complex conductivity of a ~380 nm-thick polycrystalline MgB2 film with the critical temperature (Tc) of 39.…
Disorder induced collapse of the electron phonon coupling in MgB observed by Raman Spectroscopy
K. A. Yates, G. Burnell, N. A. Stelmashenko +4
The Raman spectrum of the superconductor MgB has been measured as a function of the Tc of the film. A striking correlation is observed between the onset and the frequ…
