Atomristor - memristor effect in atomically thin nanomaterials

Tue, 01/02/2018 - 12:06
In trying to bring brain-like (neuromorphic) computing closer to reality, researchers have been working on the development of memory resistors, or memristors, which are resistors in a circuit that 'remember' their state even if you lose power. Now, scientists have discovered non-volatile memory effect in atomically thin 2D materials such as MoS2. This effect is similar to memristors or RRAM in metal oxide materials. These devices can be collectively labeled atomristor, in essence, memristor effect in atomically thin nanomaterials or atomic sheets.
