Abstract
Hydrogen was adsorbed on evaporated nickel films, and the change in electric conductivity and photoelectric emissivity was investigated. It was found that hydrogen adsorption on extremely clean nickel surfaces causes an immediate decrease in conductivity and an increase in work function. On contaminated films, however, the adsorption is slow and its effects on conductivity and work function are of opposite sign; i.e., work function is decreased and conductivity is increased.Keywords
