摘要：
The work functions phi(omega) of MgO single crystals with its respective orientation (111), (200), and (220) have been investigated from their ion-induced secondary electron emission coefficient gamma, respectively, using various ions with different ionization energies in a gamma-focused ion beam system. The work function phi(omega) for MgO single crystal with (111) orientation has the lowest value, 4.22 eV, whereas it is 4.94 eV for (200) and the highest value is 5.07 eV for (220). These work functions of MgO single crystals can explain the nonzero values of the ion-induced secondary electron emission coefficient gamma for Xe+ ions, whose ionization energy is 12.13 eV.
