Unique Constant Phase Element Behavior of the Electrolyte–Graphene Interface [PDF]
We report a unique constant phase element (CPE) behavior ( 1 Z = Q 0 ( j ω ) α ) of the electrolyte−graphene interface with both Q 0 and α showing dependence on the gate voltage.

Revealing the role of the constant phase element in relaxor ferroelectrics
Relaxor ferroelectrics are a type of material exhibiting electrostriction whereby a change in the material shape occurs under an applied electric field; however, although known by the community for many years the underlying mechanisms of the phenomenon ...
