Annotation | In present work we developed new memristive devices of sandwich-type Ni/TiOx/p-Si/Ni and planar one Ni/TiOx/p-Si/TiOx/Ni. A pinched hysteresis loop is observed for both device configurations and depends on supplementary illumination by UV/visual light. Besides classical model of migration of oxygen vacancies in titanium oxide we considers the impact of barrier modulation and recharging of surface states in TiOx/Si interface when voltage is applied to the structure in the dark or under illumination. The elaborated heterostructures show great potential as a low cost material for embedding memristive memory for large area electronics, compatible with Si CMOS process and can be managed by external illumination. |
