We report microstructures of superconducting YBa sub 2 Cu sub 3 O sub (7-x) thin films epitaxially grown on SrTiO sub 3 (100) substrate.

We have investigated the microstructure related to the charge and orbital ordering in the manganites Pr sub (0.5) Ca sub (0.5) MnO sub 3 by transmission electron microscopy.

Composite In/InO sub x films are reproducibly fabricated with two classes of microstructure, islanded at low oxide content and amorphous-composite at high oxide content.

Of the various theories so far put forward to account for the unusually high T sub c of Ba sub 2 YCu sub 3 O sub 6.9, several rely on a proposed reduced dimensionality of this system.

The upper critical field of most polycrystalline NbN thin films is anisotropic, with the perpendicular critical field H(c2)(perpendicular) larger than the parallel critical field H(c2)(parallel).

We present several applications of microstructured optical fibers and study their modal characteristics by using Bragg gratings inscribed into photosensitive core regions designed into the air-sili

A transmission electron microscope was used to characterize the microstructure of Te(.26)Fe(.74) and Fe films obtained by magnetron and dc diode sputtering techniques.

A system is described based on triangulation for making accurate, three dimensional coordinate measurements over size ranges appropriate for robot calibration, maintenance and diagnosis.

The electron beam parameters of an energy tunable (11-22 MeV) circular microtron accelerator are measured to be close to that required for free electron laser (FEL) operation in the far infrared.

The electrodeposition conditions that contribute to microvoid formation during isothermal aging of Pb-free solder-electrodeposited copper were evaluated in a systematic series of processing experim
