7. 5. Properties of Multifunctional Oxide Thin Films Despostied by Ink-jet Printing

   Författare :Mei Fang; Lyubov Belova; K. Venkat Rao; Gillian Gehring; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ink-jet printing; oixde; thin film; ink; suspension; dye sensitized solar cell; functional properties; magnetism; diluted magnetic semiconductors;

   Sammanfattning : Ink-jet printing offers an ideal answer to the emerging trends and demands of depositing at ambient temperatures picoliter droplets of oxide solutions into functional thin films and device components with a high degree of pixel precision. It is a direct single-step mask-free patterning technique that enables multi-layer and 3D patterning. LÄS MER
