Semiconductors can exhibit electrical instabilities like
current runaway, threshold switching, current filamentation,
or oscillations, when they are driven far from thermodynamic
equilibrium. This book presents a coherent theoretical des-
cription of such cooperative phenomena induced by generation
and recombination processes of charge carriers in semicon-
ductors.
