Drift velocities of charge carriers in polycrystalline diamonds were measured by a self-triggered time-of-flight (TOF) method with alpha particles based on a radiation measurement technique. Based on these measured results, a synthesis method for pol

We fabricated vacuum ultraviolet (VUV) sensors using highly oriented diamond (HOD) films and studied their long-term stability to evaluate the feasibility of the sensors for practical use. The sensors are composed of a pair of interdigitated Pt elect

To develop electron beam sources of carbon materials, field emission patterns were observed in three different setups. The first was a diode-type, in which a carbon specimen was facing to a positively biased fluorescence plate. The second was a triod
