Claim 2:
3. A method of forming an electron amplifier comprising:
providing an electron amplifier substrate, having a resistance, within an atomic layer deposition reactor; and
depositing a barrier layer selected from a group comprising Al2O3, MgF2, CaF2, MgOxFy, where x is greater than 0 and less than 1 and y is greater than 0 and less than 2(1−x), by an atomic layer deposition process including at least one cycle of:
pulsing a first metal precursor into the reactor for a first metal precursor pulse time;
purging the reactor of the first metal precursor;
pulsing a second precursor into the reactor for a second precursor pulse time; and
purging the reactor of the second precursor.
