Tunneling conduction in dense silicon quantum dot/poly (methyl methacrylate) composites

► Achieved 72% loading of silicon quantum dots in Poly(methyl methacrylate) ► Demonstrated space charge limited current (SCLC) at low bias ► SCLC is due to “free” carriers, but exhibits a weak temperature dependence. ► At high field current is limited by trap assisted tunneling.
