Silicon optical nanocrystal memory
We describe the operation of a silicon optical nanocrystal memory device. The programmed logic state of the device is read optically by the detection of high or low photoluminescence intensity. The suppression of excitonic photoluminescence is attributed to the onset of fast nonradiative Auger recombination in the presence of an excess charge carrier. The device can be programmed and erased ele...
متن کاملOptimizing Silicon Oxide Embedded Silicon Nanocrystal Inter-particle Distances
We demonstrate an analytical method to optimize the stoichiometry and thickness of multilayer silicon oxide films in order to achieve the highest density of non-touching and closely spaced silicon nanocrystals after annealing. The probability of a nanocrystal nearest-neighbor distance within a limited range is calculated using the stoichiometry of the as-deposited film and the crystallinity of ...
متن کاملModeling miniband for realistic silicon nanocrystal array
Within the envelop-function framework, we developed the finite element method to calculate theminibands in the realist Silicon nanocrystal array. This method clearly reveals the miniband formation and accurately calculates the E–K dispersion relationship. In the simple 1D array, the deduced miniband structure matches well with the analytic Kronig–Penney method. More importantly, it can better s...
متن کاملCdSe nanocrystal quantum-dot memory
Memory effects in the electronic transport in CdSe nanocrystal sNCd quantum-dot arrays have been observed and characterized. Conduction through a NC array can be reduced with a negative voltage and then restored with a positive voltage. Light can also be used to restore or even increase the NC array conduction. We have studied the switching of the conduction in CdSe NC arrays and found the beha...
متن کاملSynthesis and characterization of aerosol silicon nanocrystal nonvolatile floating-gate memory devices
This letter describes the fabrication and structural and electrical characterization of an aerosol-nanocrystal-based floating-gate field-effect-transistor nonvolatile memory. Aerosol nanocrystal nonvolatile memory devices demonstrate program/erase characteristics comparable to conventional stacked-gate nonvolatile memory devices. Aerosol nanocrystal devices with 0.2 mm channel lengths exhibit l...
