Mechanism and improvement of Y_2O_3 cathode in DC-PDP

Mizumoto USHIROZAWA, Yoshimichi TAKANO
1999 ITE Technical Report  
: Conduction mechanism is necessary so that Y203 which is an insulator may work as a cathod ( ・ of DC − PDP In order to clarify the mechanism thin fllm Y203 / AI structure cathodes are exa 皿 illed . As the resuit , 1t seemed to prove the 飴ct next . Many cracks are fbrmed inY203 by the high ・ temp ( 聖 rature process . From the crack , AI cathode bus line is sputt 沿 red in aging . The Y203 surface is cover ( ⊇d thiniy with this Al and a conduction path is 量 brmed . In the meantime , the crack
