Van der Waals Heterostructures by Design: From 1D and 2D to 3D

Recent progress on van der Waals heterojunctions applied in photocatalysis

“…4. 69 Compared with traditional semiconductor heterostructures, vdWHs do not depend on chemical bonds and are not limited by the lattice compatibility of the materials. VdWHs are physically assembled by relatively weak van der Waals interaction forces.…”

“…70 The interaction strength is generally of the order of 0.1–10 kJ mol −1 , which is 2–3 orders of magnitude less than that of ionic or covalent bonds (about 100–1000 kJ mol −1 ). 69 The heterostructure based on vdW material has the unique advantages of tight interface and suitable energy band structure, which can realize interlayer interface charge transfer and separation under the action of vdW forces. The heterostructure can be formed on the unbonded surface, and because of the excellent optical, electrical, thermal and magnetic effects of vdWHs formed by the stacking of vdW materials, vdWHs can be widely applied in the fields of electronics, optoelectronic devices, semiconductors, photocatalysis and electrocatalysis.…”

Dipole-improved gating of azulene-based single-molecule transistors

“…[5][6][7] Due to the inherently small size of the single-molecule FET, it has the potential to extend Moore's law to the single-molecule level, breaking the development bottleneck of device miniaturization. [8][9][10][11][12] Meanwhile, it is also a powerful tool for exploring quantum transport and novel physical phenomena. [13][14][15][16][17][18][19] Therefore, single-molecule FETs have been widely studied.…”

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

“…The construction of single-molecule electronic devices is a promising approach to overcome Moore's law and improve the integrated circuit technology. [31][32][33][34][35] In comparison with two-terminal molecular devices, single-molecule FETs, in which a single molecule acts as the tunable charge transport part in threeterminal device configurations, are the key components for further integration of molecular-level electronic circuits. According to the types of gates, such as solid and liquid gates, and generalized gates with external stimuli, we divide single-molecule FETs into three categories in this review.…”
