Microneural Network System Based on MoS2/h-BN/Graphene van der Waals Heterojunction Transistor

“…17 Due to the synergistic effect of graphene and h-BN, our MoS 2 /h-BN/graphene vdW heterojunction transistor achieves the highest electron mobility of 340 cm 2 /(V•s) at room temperature. 18 With the temperature decreases (<100 K), the scattering mechanism in the MoS 2 transistor and MoS 2 /graphene transistor gradually shifts from lattice scattering to impurity scattering, leading to a decrease in their mobility. However, in our MoS 2 /h-BN/graphene vdW heterojunction transistor, due to the presence of h-BN, the scattering mechanism remains unchanged and lattice scattering always dominates.…”

“…The μ is calculated by μ = 1 C normali L W g normalm V ds , where C i is the gate oxide capacitance per unit area, L is the channel length, W is the channel width, and g m = d I ds /d V g is the transconductance . Due to the synergistic effect of graphene and h-BN, our MoS 2 /h-BN/graphene vdW heterojunction transistor achieves the highest electron mobility of 340 cm 2 /(V·s) at room temperature .

Recent Progress on Nickel- and Iron-Based Metallic Organic Frameworks for Oxygen Evolution Reaction: A Review

“…Liu et al 108 demonstrate that a 2D CoNi-MOF array built directly on a Cu substrate with a reduced overpotential value (265 mV at 10 mA cm −2 ) is a highly stable and efficient electrocatalyst for the OER in an alkaline medium. As OER catalysts, composite bimetallic phosphides produced from MOF were created by Lin et al 109 The complex production method of MOF-derived bimetallic phosphides still prevents their additional advancement in OER, despite their remarkable electrocatalytic activity. These catalysts can be found in alloys, nitrides, phosphides, oxides, hydroxides, etc.…”

NiFeP nanosheets for efficient and durable hydrazine-assisted electrolytic hydrogen production

“…Besides, P atoms on the surface of TMPs can induce a partial negative charge to accept protons, which can greatly improve the HER in alkaline media. 30,31 Bimetallic phosphides have the advantages of good adjustability, synergistic effects and composition diversity, which provide the possibility for further enhancement of the electrocatalytic activity. However, there are relatively few studies on their catalytic properties in the HzOR.…”
