The chemistries and structures of both embedded and extracted Y Ti O nanometer-scale oxides in a nanostructured ferritic alloy (NFA) were probed by x-ray absorption spectroscopy (XAS). Y2Ti2O7 is the primary embedded phase, while the slightly larger

The authors report using a combination of ion-implantation exfoliation and femtosecond laser ablation to fabricate thin (micrometers-thick) single-crystal films of a complex oxide, LiNbO3. The process physics for the method is bounded by the threshol

Fabrication of a bilayer HfO{sub 2}/single-crystal LiNbO{sub 3} film is demonstrated using deep high-energy He{sup +} implantation in a LiNbO{sub 3} wafer, followed by HfO{sub 2} atomic layer deposition, and, then, selective etching exfoliation from

The nature of a striking pattern of extended defects formed by very high dose implantation of helium in a complex oxide, for example, ferroelectric$z$-cut LiNbO${}_{3}$, is studied. After irradiation, a high concentration of defects is found to colle

Large-area ferroelectric nanodomain patterns, which are desirable for nonlinear optical applications, were generated in previously He-implanted lithium niobate crystals by applying voltage pulses to the tip of a scanning force microscope. The individ

High-Power Laser Ablation VII.
We report femtosecond laser cutting of ultrathin ferroelectric sheets. This process enables one to do rapid patterning of microns-thick films of complex oxides such as LiNbO3, which are obtained via ion-beam exfoliation from standard wafers. Cutting

We demonstrate room-temperature phase matching of second-harmonic generation by waveguide dispersion (WGD) in 3-mum-thick LiNbO3 membranes. The membranes were made using patterned deep-ion-implantation-guided etching.

The {sup 44}Ti(t{sub 1/2}=59 yr) nuclide, an important signature of supernova nucleosynthesis, has recently been observed as live radioactivity by {gamma}-ray astronomy from the Cas A remnant. We investigate in the laboratory the major {sup 44}Ti pro
