Abstract The secondary electron emission (SEE) properties of Zn-doped MgO thin films (~700 nm thickness) grown via electron-beam evaporation have been studied based on Paschen curve measurements. The Zn-doped (1 at.%) MgO film shows an improved SEE coefficient (γ) compared to that of non-doped MgO from 0.02 to 0.05 in the 100 V Pa−1 m−1 region. The origin of a superior γ is due to the reduction in the band-gap from 6.79 eV to 6.26 eV (the values are measured via ultra-violet photoemission… CONTINUE READING
