abstract = {Controlling movements of electrons and holes is the key
task in developing today's highly sophisticated information
society. As transistors reach their physical limits, the
semiconductor industry is seeking the next alternative to
sustain its economy and to unfold a new era of human
civilization. In this context, a completely new information
token, i.e., ions instead of electrons, is promising. The
current trend in solid‐state nanoionics for applications
in energy storage, sensing, and brain‐type information
processing, requires the ability to control the properties
of matter at the ultimate atomic scale. Here, a conceptually
novel nanoarchitectonic strategy is proposed for controlling
the number of dopant atoms in a solid electrolyte to obtain
discrete electrical properties. Using α‐Ag2+δS nanodots
with a finite number of nonstoichiometry excess dopants as a
model system, a theory matched with experiments is presented
that reveals the role of physical parameters, namely, the
separation between electrochemical energy levels and the
cohesive energy, underlying atomic‐scale manipulation of
dopants in nanodots. This strategy can be applied to
different nanoscale materials as their properties strongly
depend on the number of doping atoms/ions, and has the
potential to create a new paradigm based on controlled
single atom/ion transfer},
