Electronic conductivity of semiconductor nanoparticle monolayers at the air/water interface

Article Abstract:

The electronic conductivity of PbS and CdTe nanoparticle monolayers was examined voltammetrically by using interdigitated array (IDA) electrodes at the air/water interface. The conductivity of the final interfinger deposits was about two orders of magnitude smaller than that for pure metallic lead, indicating some surface contamination and/or less than perfect crystalline structure.

A versatile chemical strategy for ultrafine AlN and Al-O-N powders

Article Abstract:

A versatile low-temperature chemical approach utilixing an alkoxide-based hydrazide process was developed for the synthesis of nanometer-size aluminum nitride, oxynitride, and composite powders. This versatile chemical processing strategy developed can also be used to synthesize nanocrystalline nitride and oxynitride of oxophilic elements such as Al.
