Rapid thermal annealing temperature dependence of noise properties in Au/n‐GaAs Schottky diodes with embedded InAs quantum dots in asymmetric In0.2Ga0.8As wells
Abstract:The effect of rapid thermal annealing temperature on the trap properties of Au/n‐GaAs Schottky diodes with embedded InAs quantum dots in asymmetric In0.2Ga0.8As wells have been investigated by capacitance–voltage (C –V) and low frequency noise (LFN) measurements in both reverse and forward bias regimes. The current noise spectra show 1/f behaviour and generation–recombination (g–r) noise, attributed to uniformly distributed traps in energy and to a discrete trap level in the energy band‐gap of the GaAs capping… 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.
