Multi-valued logic system: new opportunities from emerging materials and devices

Abstract

Multi-valued logic (MVL) is considered as a key enabler for next-generation and high-information-density digital electronics. While the conventional approaches to MVL systems rely on circuit-level design and implementation, the emergence...

Flexible Graphene-Channel Memory Devices: A Review

“…Such a problem becomes often more severe in two-terminal diode-type devices, for which a self-rectification scheme can be one of the possible solutions . Also, further improvement in memory capacities can possibly be made by exploring the possibilities of integrating these flexible graphene devices with the multivalued logic architecture, which is another emerging concept in electronics to maximize the in-device digital information density . Also, an applicable device technology should meet the strict requirements for energy consumption, data communication, and display methods.…”

Recent device-circuit integration approaches might be applicable to wearable graphene technologies, powered, for instance, by ambient energy harvesting, solar-power generation, and IoT user interfaces.…”

High-performance multivalued logic circuits based on optically tunable antiambipolar transistors

“…[15][16][17][18][19] A wide variety of twodimensional (2D) materials and organic semiconductors have already been investigated with a view to further improve the device performance of the AATs and MVLs. [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] In most of the studies transition metal dichalcogenides (TMDCs) such as molybdenum disulfide (MoS 2 ), tungsten diselenide (WSe 2 ) and tin diselenide (SnSe 2 ) were employed owing to their advantages of dangling bond free surface properties, superior electronic performance metrics and high stability under mechanical stress. [20][21][22][23][24][25][30][31][32][33][34][35][36][37] However, TMDCs have a fatal disadvantage as regards to their film processing method.…”

Electrochemical Potential‐Driven High‐Throughput Molecular Electronic and Spintronic Devices: From Molecules to Applications

“…They are endowed with properties suitable for information storage and processing, and complex logic operation and can withstand high operational voltages. [9][10][11][12][13][14] Small molecules can form the primary building blocks of different kinds of biomacromolecules,p olymers,a nd framework materials like metal-organic frameworks and covalent organic frameworks on various surfaces. [15][16][17][18][19][20] Researchers have directed increasing attention towards immobilizing molecules on electrode surfaces;t he thickness,c hemical composition, morphology, structural properties,a nd electronic functionality of these layers can be controlled through asystematic chemical approach.…”
