Outline of Final Research Achievements |
Using ECR plasma as a background, the transport and deposition of tungsten particles during ablation in composite PLD were confirmed. Additionally, the use of oxygen plasma led to the formation of tungsten oxide thin films, demonstrating that deposition with chemical reactions is possible. A composite PLD system with a magnetron plasma source was also established, successfully fabricating LiCoO3 thin films and demonstrating the effect of oxygen plasma in reducing oxygen vacancies.
