Query: Full Counting Statistics of Andreev Tunneling   We employ a single-charge counting technique to measure the full counting
statistics (FCS) of Andreev events in which Cooper pairs are either produced
from electrons that are reflected as holes at a superconductor/normal-metal
interface or annihilated in the reverse process. The FCS consists of quiet
periods with no Andreev processes, interrupted by the tunneling of a single
electron that triggers an avalanche of Andreev events giving rise to strongly
super-Poissonian distributions.
