Field-assisted (FA)-oxygen etching is known as a method to change a typical tungsten (W) needle into highly coherent field emitters with tip apexes composed of countable atoms. On the other hand, although less known, the method also causes a peculiar electron emission characterized by extremely low biases with a very low frequency. In this study, we are aiming at the reproducible occurrence of the low-bias electron emission. So far, we found that effective is two-step process of FA-water etching followed by FA-oxygen one, which once caused the peculiar electron emission with low bias of 16 V. |
