Abstract:It is pointed out that the determination of the midgap density of states in amorphous semiconductors using the space-charge-limited-current method is reliable only when the density of states is less than 10'' ern+ eV-l and the electrode spacing is in the order of pm. Beyond these restrictions the current will be affected by the Poole-Frenkel effect which will distort the determination of density of states from current-voltage characteristics.Es wird gezrigt, da5 die Bestimmung der Midgap-Zustandsdichto in anio… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
