This paper describes synthesis of ultrathin pinhole-free insulating aluminum oxide layers for electronic device protection in corrosive liquid environments, such as phosphate buffered saline (PBS) or clinical fluids, to enable emerging biomedical applications such as biomolecular sensors. A pinhole-free 25-nm thick amorphous aluminum oxide layer has been achieved using ultra-high vacuum DC magn...

High quality patterning of single-walled carbon nanotube (SWCNT) transparent conductive films is achieved by a lift-off aluminum interlayer method, which has the advantage of resulting in contamination-free and damage-free SWCNTs. The obtained patterns preserve the electrical properties of the SWCNT films and show promising applications in flexible high frequency electronic and display devices.
