Distortion-Dependent Raman Spectra and Mode Mixing in RMnO3 Perovskites
M. N. Iliev, M. V. Abrashev, J. Laverdiere +4
The polarized Raman spectra of orthorhombic RMnO3 series (R=La,Pr,Nd,Sm,Eu,Gd,Tb,Dy,Ho,Y) were studied at room temperature. The variation of phonon frequencies with R ionic radius…
Chain-oxygen ordering in twin-free YBa2Cu3O6+x single crystals driven by 20 keV electron irradiation
H. W. Seo, Q. Y. Chen, M. N. Iliev +5
We have examined the effects of 20 keV electron irradiation on [-Cu(1)-O(1)-]n chain oxygen arrangements in oxygen deficient but otherwise twin-free YBa2Cu3O6+x single crystals. Co…
Characterizations of strain and defect free GaN nanorods on Si(111) substrates
H. W. Seo, Q. Y. Chen, M. N. Iliev +4
GaN-nanorods grown on Si(111) substrates are found strain- and defect-free as characterized by micro Raman spectroscopy, secondary electron (SE) and cathode-luminescence (CL) imagi…
Epitaxial GaN Nanorods via Catalytic Capillary Condensation
H. W. Seo, Q. Y. Chen, L. W. Tu +3
Intrinsic catalytic process by capillary condensation of Ga-atoms into nanotrenches, formed among impinging islands during the wurzite-GaN thin film deposition, is shown to be an e…
