The Charge State of Hydrogen Ions in Metals and Semiconductors

The charge state of H ions in metals such as tungsten, Ni and Au and semiconductors has been studied based on a comparison of H ion stopping cross-sections in metal and semiconductor targets. It is shown that neutralization of the H ion in metal and semiconductors at ion speeds v sub i approx = (1-2...

Zusammenfassung:The charge state of H ions in metals such as tungsten, Ni and Au and semiconductors has been studied based on a comparison of H ion stopping cross-sections in metal and semiconductor targets. It is shown that neutralization of the H ion in metal and semiconductors at ion speeds v sub i approx = (1-2)v sub 0 , where v sub 0 = 2.2 x 10 exp 8 cm/s, is due to different mechanisms, i.e. to a bulk effect in metals and to a subsurface effect in semiconductors.
