Modulation of capacitance magnitude by charging/discharging in silicon nanocrystals distributed throughout the gate oxide in MOS structures

In this work, charge trapping in silicon nanocrystals (nc-Si) distributed throughout the gate oxide in a metal oxide semiconductor (MOS) structure has been studied. This situation is different from the conventional one with nc-Si confined in a narrow layer embedded in the gate oxide. In the latter,...

description In this work, charge trapping in silicon nanocrystals (nc-Si) distributed throughout the gate oxide in a metal oxide semiconductor (MOS) structure has been studied. This situation is different from the conventional one with nc-Si confined in a narrow layer embedded in the gate oxide. In the latter, charge trapping in nc-Si leads to a shift in capacitance-voltage characteristic (i.e., a change in the flat-band voltage). In contrast, in the former the charge trapping leads to a dramatic reduction in the MOS capacitance. The original capacitance could be recovered after the release of the trapped charges by a small bias, UV light illumination, or low-temperature thermal annealing.
