- 論文の詳細を見る
To obtain a good field emission (FE) performance, the shape of a Pd/W tip substrate with carbon nanofibers is optimized. We succeeded in maximizing FE current by adjusting the apex angle of the tip. When the apex angle of the tip substrate is nearly 50°, a high FE efficiency and a narrow divergence emission angle for the convergence of the electron beam are obtained, which can be potentially used for the cathode of electrical devices with a low power consumption and a high FE efficiency.
