I-V & C-V characteristics of ferroelectric lead germanate on silicon

Abstract
The ferroelectric properties of lead germanate film on silicon substrates seemed to be influenced by the nature of the interface. I-V studies revealed the formation of an iso-type n-n+ hetero - junction at low voltages, exhibiting two types of conduction: generation-recombination followed by tunneling. C-V studies show a hysteresis indicating a nonvolatile memory behavior.
