Abstract

The thermionic work functions and the Richardson constants for LaB//6 single crystals are measured using a diode system with a guard ring under stable thermionic conditions. They are 2. 86 plus or minus 0. 03 eV, 82 A/Cm**2K**2 for the (100) plane, 2. 68 plus or minus 0. 03 eV, 57 A/cm**2K**2 for the (110) plane, and 3. 4 plus or minus 0. 2 eV, 71 A/cm**2K**2 for the (111) plane. The (111) faceting on the (110) plane has an important effect on the reduction of the thermionic current from the (110) plane at 5 multiplied by 10** minus **6 Torr.
