Recent progress in single-molecule transistors: their designs, mechanisms and applications

Abstract

A single-molecule field-effect transistor (FET) is the key building block of future electronic circuits. At the same time, a single-molecule FET is also a unique platform for studying physical mechanisms...

Photo‐Responsive Molecular Junctions Activated by Perovskite/Graphene Heterostructure Electrode

“…[1][2][3][4][5][6][7][8] Many significant developments have been made to utilize single or bundles of molecules as electronic components such as molecular wires, rectifiers, transistors, memories, switches, and thermoelectric devices. [9][10][11][12][13][14][15][16][17][18] Regardless of the types of devices, it is crucial to understand and control the charge transport characteristics through molecular junctions. Charge transport phenomena in molecular junctions are influenced by not only the electrical characteristics of molecules but also the interactions that occur at the interfaces between molecules and electrodes.…”

Light-Driven Charge Transport and Optical Sensing in Molecular Junctions

“…Many interesting transport phenomena in MJs have been reported to date, including the transistor (or gating) effect [15][16][17][18], conductance switching [19][20][21], thermal [22,23], thermoelectricity [24,25], photoswitching [26][27][28] and spintronics [29][30][31][32][33]. While most of these topics have been previously reviewed [34][35][36], we, in this work, will focus our attention on the optoelectronic phenomena in MJs, a topic that has been rarely surveyed in detail yet is rather important for furthering the development of the field. Light-matter interactions in illuminated MJs have drawn increasing amounts of attention in recent Nanomaterials 2022, 12, 698 2 of 27 years due to many exciting potential applications associated with them, such as photovoltaics [37,38], organic light-emitting diode [39][40][41], chemical/bio-detection [42][43][44][45], and plasmonics [46][47][48].…”

Breakdown Voltage and Linear Temperature Drift in a Single-Molecule Junction

“…Because of the potential applications in electronic devices, the properties of single molecules connected to macroscopic electrodes have been studied intensively [1][2][3][4][5][6][7][8][9][10][11], and this research field-known as molecular electronics [12]-is one of the most exciting. The use of individual molecules as functional units in electronic devices has been reported for decades [1,10,11,[13][14][15][16][17][18][19][20][21][22].…”

“…Single-molecule transport behavior is very important for the further development of molecular electronics, and transport behaviors that depend on temperature and bias voltage are useful for distinguishing among conduction mechanisms [12,28,29]. The relationships between molecular conductance and (i) temperature and (ii) bias voltage have been investigated [8,[10][11][12]15,20,26,[30][31][32],…”
