Materials Research Express, 10(11) 115201-115201, Nov 1, 2023 Peer-reviewedLast authorCorresponding authorAbstract The shape of conductive filaments in CBRAM is important for resistance switching and conductance modulation, especially in applications like neuromorphic and reservoir computing that use conductance as weight. We report on RF-induced modulation of CBRAM using Ge2Sb3.4Te6.2 with sheet-like filaments and compared it to those with dendritic filaments. RF input below 100 MHz reduced SET and RESET voltages, similar to CBRAM with dendritic filaments, but showed significantly different resistance changes. Repeated RF on/off input gradually increased the resistance of low-resistance state, unlike the dendritic filament CBRAM, where the resistance decreased. The increased resistance suggests RF-induced denser sheet-like filaments. Furthermore, the resistance of the high-resistance state showed a peculiar RF-induced resistance change not observed in dendritic filaments. The resistance decreased during RF input and increased to nine times the initial value when RF was switched off. The results show that the conductance modulation by RF input strongly depends on the filament type.

Technical report of IEICE. LQE, 112(62) 21-24, May 18, 2012We observed excitonic and biexcitonic Rabi oscillation by using single photoexcited telecommunication-band quantum dot via photocurrent measurements. The biexcitonic population oscillates sinusoidally with the square of the pulse area while the excitonic population oscillates with the pulse area. The pulse area dependence clearly shows that the biexcitonic Rabi oscillation is caused by two-photon absorption. These results demonstrate that the telecom-band excitonic and biexcitonic system is promising for exciton based-quantum information devices compatible with optical fiber networks.
