Model for oscillations in the guidance of ions through insulating nanocapillaries
Pokhil, G.; Merabet, H.; Stolterfoht, N. ( IOP Publishing , 2011 , Conference Paper)The pre-equilibrium period of the ion guiding through insulating nanocapillaries is characterized by the production of temporary charge patches inside the capillaries. The dynamics of the charge patch creation is revealed ... -
