Permittivity?  It relates induced polarization -- the charge stored in a 
cap -- to the applied electric field.  There are different kinds of hi-k 
caps.  Hi-k ceramics operate close to the ferroelectric phase transition, 
which gives them a large temperature coefficient and make control of the 
cap value difficult.
