Research output: Patent


Patterned multilayer films, such as those used in electronic devices, solar cells, solid oxide fuel cells (SOFCs), and solid oxide electrolysis cells (SOECs) may be deposited and annealed in a single tool. The tool includes an inkjet printer head, a heater, and a laser. The inkjet printer head deposits on a substrate either suspended particles of a functional material or solvated precursors of a functional material. The head is mounted on a support that allows the head to scan the substrate by moving along the support in a first direction and moving the support along a second direction. After the head deposits the material the heater evaporates solvent from substrate, and the depositing and heating may be repeated one or more times to form a patterned multilayer material. Then, a laser, microwave, and/or Joule effect heating device may be used to anneal the multilayer material to a desired pattern and crystalline state.
