Abstract (in Japanese) (See Japanese page) 
(in English) High brightness and stable cathode has been required for SEM use. Tungsten based field emission cathode(W-FE) has been used for SEM as high brightness and narrow energy distribution cathode compare with thermal emission. However, single crystal W-FE has some problems, that is expensive and complex for modification by regular flashing process. In order to overcome these problems, we have been studied about Tungsten Carbide(WC) field emission cathode. WC is known as low workfunction material. In this work, we report the process of carbonizing and I-V characteristics of WC-FE.
