Characteristics at high electric fields in amorphous Ge2Sb2Te5 films
Source abstract
Abstract
Abstract Current–voltage ( I – V ) characteristics have been studied in as-deposited amorphous Ge 2 Sb 2 Te 5 films. At low electric fields, ohmic behavior is observed. On the other hand, at high electric fields ( E > 10 6 V/m) the current becomes non-ohmic. Analysis of the data shows the existence of Poole–Frenkel conduction in which ln I vs V 1/2 curves are found to be straight lines. Pre-switching behaviors are also discussed from electrode configuration.
