In this research, Arc CNTs’ field emission characteristic is better than CVD CNTs’, the result makes us to know that structure is very important. We also packaged the cathode to measured the I-V curve in a 17-inch CRT using the traditional method, and find a good result. Finally, we use nanosize Silver particle, because find a problem by SEM. And we believe the method can be better than previous method. Senfar Wen 溫盛發 2002 學位論文 ; thesis 80 zh-TW |
