The grain structure is compared for films of the organic semiconductor 6PTTP6 prepared in the open air and in a closed, static atmosphere saturated with xylene vapor.

Mesoscopic (500-2000 Angstrom) and microscopic (5-20 Angstrom) phase segregation with temperature and magnetic field was studied in the model manganite Pr0.7Ca0.3MnO3 by high-resolution neutron dif

We derive the sigma model for granular metals. It is valid for any relation between the temperature T and the grain mean level spacing.

We present a description of granular dynamics based on the idea of differentiation between fluid and solid components. First, we construct a model of completely fluidized phase.

We have been studying sub-micron sized wires and rings constructed from 400-600angstroms thick 1--- ppm CuMn material at temperatures down to 10 mK.

Two fundamental extensions to the function of previously described fully field effect two-dimensional (2D) electron heterostructures are presented.

The ability to construct mesoscopic devices with control of local electron densities on high mobility heterostructures is important to the advancement of reduced dimensional electronic system physi

By using dark-field real-space imaging technique of transmission electron microscopy (TEM), we have observed slow 200angstroms-scale fluctuations of charge-ordered (CO) phase in mixed-valent mangan

Using high dose implantation of 200 KeV Co ions followed by high temperature annealing, we have created buried layers of CoSi sub 2 in crystalline Si of both (100) and (111) orientations.

Recent progress in the growth of thin epitaxial silicides on silicon has resulted in films of very high quality with especially smooth interfaces [1].
