Figure 3From: Stable Field Emitters for a Miniature X-ray Tube Using Carbon Nanotube Drop Drying on a Flat Metal TipSEM images of various CNT emitters fabricated by changing the ratio of CNT to Ag NP and the concentration of the mixture drop. The concentration of CNT and Ag NP in isopropyl alcohol is a 0.085 and 0.17 w%, b 2.1 and 4.2 w%, c 0.17 and 0.17 w%, d 4.2 and 4.2 w%, and e 0.64 and 0.85 w%.
