Abstract

The resonant tunneling via nanoscale silicon particles embedded in an a-SiO2 matrix in a diode structure has revealed a range of intriguing observations such as extremely sharp peaks and steps and periodic oscillations in (conductance-voltage) G-V measurements. Recently we have discovered a drastic sharpening of the conductance peak with light. Phase measurements show that the effects of light may be understood by invoking the filling of charged traps.
