Energy-Efficient ReS₂-Based Optoelectronic Synapse for 3D Object Reconstruction and Recognition

A synapse with low power consumption based on MoTe2/SnS2 heterostructure

“…The transfer characteristics at V g of 0.1 V is display in the inset of figure 3(f). Furthermore, as shown in table 1 in supplementary data, we compare the power consumption of the present heterojunction device with that of the reported artificial synaptic devices in the literature including both electrical synaptic devices and photonic synapses [12,13,15,19,22,32,[35][36][37][38][39][40]. It shows that the power consumption per spike of our MoTe 2 /SnS 2 heterostructure synaptic devices is in the lower class among these synaptic transistors.…”

“…In recent years, synaptic devices based on two-dimensional (2D) materials, such as grapheme [8][9][10] and transitionmetal dichalcogenides including MoS 2 [11][12][13], WSe 2 [14][15][16][17], WS 2 [18,19], and InSe [20][21][22] have been successfully developed and exhibited excellent charge storage performance. 2D materials have great potential for highperformance devices with high-density integration and low power consumption due their atomic thickness, absence of lattice mismatch, and compatibility with conventional device technologies.…”

An Organic Optoelectronic Synapse with Multilevel Memory Enabled by Gate Modulation

“…In recent developments, materials such as perovskite, metal oxides, organic materials, , and low-dimensional materials ,− have been employed to execute optoelectronic synaptic functions, highlighting a significant progression in this field. Organic semiconductors (OSCs) stand out due to their combined advantages, such as being lightweight, having high light absorption coefficients, and having large-scale processability .…”
