Abstract
IT has been postulated1 that the negative charge accumulated on zinc oxide layers under the influence of a corona discharge is due to negative ions (the electrofax process). Since then it has been suggested on several occasions that oxygen negative ions play a dominant role in the charging and discharging of zinc oxide surfaces2,3 even in thermostimulated conditions4. (Thermostimulated emission is the burst of negative particles leaving a surface heated at a constant rate at a given temperature.)
