project LOTOP (LOw Temperature Oxide Precursors)

Targets
  • printed oxides on flexible substrates
  • molecular precursors not nano-particles
 

Materials
  • transparent conducting oxides
  • amorphous oxide semiconductors
  • passivation layers
 

Strategy
  • synthesise oxide motif compounds
  • convert to oxide by ether elimination
  • thermodynamically favoured route
  • identify low temperature trigger

Oxide motif compounds

made from parent alkoxide

contain fragment of oxide structure

choice of solvents

easily formulated inks

literature precedents
