Stable and erasable patterning of vanadium pentoxide thin films by atomic force microscope nanolithography

Long lasting colored pattern formation on sol–gel deposited vanadium pentoxide sV2O5d thin films is demonstrated by atomic force microscope sAFMd nanolithography. The films can be locally colorized by application of a positive dc bias voltage on the conductive AFM tip. The patterns can be erased, or “bleached,” by application of a negative bias voltage. The changes in optical reflectivity, topo...

Sol–gel derived PZT films doped with vanadium pentoxide

The present research investigated the sol–gel preparation, dielectric and ferroelectric properties of PZT films doped with 5 mol% vanadium oxide. Stable PZTV sols can be readily formed, and homogeneous, micrometer thick and pinhole-free PZTV films were obtained by using spin coating followed with rapid annealing. The X-ray diffraction patterns revealed that no parasitic or secondary phases were...
