Charge storage in CeO2/Si/CeO2/Si(111) structures by electrostatic force microscopy
An electrostatic force microscope was used to write and image localized dots of charge in a double barrier CeO2/Si/CeO2/Si(111) structure. By applying a relatively large tip voltage and reducing the t...

Realization of an axially aligned Au-ion source of atomic size
Nanotips are high-brightness electron sources with a principal characteristic source-size of one atom. We explore here nanotips as a type of atom-size source of Au ions. Conditions were found for a re...

Single walled carbon nanotubes (SWNTs) were dispersed in isotropic petroleum pitch matrices to form nanotube composite carbon fibers with enhanced mechanical and electrical properties. We find that the tensile strength, modulus, and electrical conductivity of a pitch composite fiber with 5 wt % loading of purified SWNTs are enhanced by ~ 90%, ~ 150%, and 340% respectively, as compared to the corresponding values in unmodified isotropic pitch fibers. These results serve to highlight the potential that exits for developing a spectrum of material properties through the selection of the matrix, nanotube dispersion, alignment, and interfacial bonding. ©1999 American Institute of Physics.
