| 1 | Atomic and Close-to-Atomic Scale Manufacturing:A Review on Atomic Layer Removal Methods Using Atomic Force Microscopy显示文摘Manufacturing at the atomic scale is the next generation of the industrial revolution.Atomic and close-to-atomic scalemanufacturing(ACSM)helps to achieve this.Atomic force microscopy(AFM)is a promising method for this purposesince an instrument to machine at this small scale has not yet been developed.As the need for increasing the number ofelectronic components inside an integrated circuit chip is emerging in the present-day scenario,methods should be adoptedto reduce the size of connections inside the chip.This can be achieved using molecules.However,connecting moleculeswith the electrodes and then to the external world is challenging.Foundations must be laid to make this possible for thefuture.Atomic layer removal,down to one atom,can be employed for this purpose.Presently,theoretical works are beingperformed extensively to study the interactions happening at the molecule-electrode junction,and how electronic transportis affected by the functionality and robustness of the system.These theoretical studies can be verified experimentally only if nano electrodes are fabricated.Silicon is widely used in the semiconductor industry to fabricate electronic components.Likewise,carbon-based materials such as highly oriented pyrolytic graphite,gold,and silicon carbide find applications inthe electronic device manufacturing sector.Hence,ACSM of these materials should be developed intensively.This paperpresents a review on the state-of-the-art research performed on material removal at the atomic scale by electrochemical andmechanical methods of the mentioned materials using AFM and provides a roadmap to achieve effective mass productionof these devices. | Paven Thomas Mathew Brian J.Rodriguez Fengzhou Fang | 2020 | Nanomanufacturing and Metrology2020，3，3： | 9 |

| 6 | Advances in Molecular Electronics:A Brief Review显示文摘The field of molecular electronics,also known as moletronics,deals with the assembly of molecular electronic components using molecules as the building blocks.It is an interdisciplinary field that includes physics,chemistry,materials science,and engineering.Moletronics mainly deals with the reduction of size of silicon components.Novel research has been performed in developing electrical-equivalent molecular components.Moletronics has established its influence in electronic and photonic applications,such as conducting polymers,photochromics,organic superconductors,electrochromics,and many more.Since there is a need to reduce the size of the silicon chip,attaining such technology at the molecular level is essential.Although the experimental verification and modeling of molecular devices present a daunting task,vital breakthroughs have been achieved in this field.This article combines an overview of various molecular components,such as molecular transistors,diodes,capacitors,wires,and insulators,with a discussion of the potential applications of different molecules suitable for such components.We emphasize future developments and provide a brief review of different achievements that have been made regarding graphene-based molecular devices. | Paven Thomas Mathew Fengzhou Fang | 2018 | Engineering2018，4，6： | 1 |

| 8 | Toward Single-Atomic-Layer Lithography on Highly Oriented Pyrolytic Graphite Surfaces Using AFM-Based Electrochemical Etching显示文摘Atomic force microscopy(AFM)-based electrochemical etching of a highly oriented pyrolytic graphite(HOPG)surface is studied toward the single-atomic-layer lithography of intricate patterns.Electrochemical etching is performed in the water meniscus formed between the AFM tip apex and HOPG surface due to a capillary effect under controlled high relative humid-ity(~75%)at otherwise ambient conditions.The conditions to etch nano-holes,nano-lines,and other intricate patterns are investigated.The clectrochemical reactions of HOPG etching should not generatc debris duc to the conversion of graphite to gaseous CO and CO_(2)based on etching reactions.However,debris is observed on the etched HOPG surface,and incom-plete gasification of carbon occurs during the etching process,resulting in the generation of solid intermediates.Moreover,the applied potential is of critical importance for precise etching,and the precision is also significantly influenced by the AFM tip wear.This study shows that the AFM-based electrochemical etching has the potential to remove the material in a single-atomic-layer precision.This result is likely because the etching process is based on anodic dissolution,resulting in the material removal atom by atom. | Wei Han Paven Thomas Mathew Srikanth Kolagatla Brian J.Rodriguez Fengzhou Fang | 2022 | Nanomanufacturing and Metrology2022，5，1： | 1 |
| 9 | Periodic energy decomposition analysis for electronic transport studies as a tool for atomic scale device manufacturing显示文摘Atomic scale manufacturing is a necessity of the future to develop atomic scale devices with high precision.A different perspective of the quantum realm,which includes the tunnelling effect,leakage current at the atomic-scale,Coulomb blockade and Kondo effect,is inevitable for the fabrication and hence,the mass production of these devices.For these atomic-scale device development,molecular level devices must be fabricated.Proper theoretical studies could be an aid towards the experimental realities.Electronic transport studies are the basis to realise and interpret the problems happening at this minute scale.Keeping these in mind,we present a periodic energy decomposition analysis(pEDA)of two potential candidates for moletronics:phthalocyanines and porphyrins,by placing them over gold substrate cleaved at the(111)plane to study the adsorption and interaction at the interface and then,to study their application as a channel between two electrodes,thereby,providing a link between pEDA and electronic transport studies.pEDA provides information regarding the bond strength and the contribution of electrostatic energy,Pauli’s energy,orbital energy and the orbital interactions.Combining this analysis with electronic transport studies can provide novel directions for atomic/close-toatomic-scale manufacturing(ACSM).Literature survey shows that this is the first work which establishes a link between pEDA and electronic transport studies and a detailed pEDA study on the above stated molecules.The results show that among the molecules studied,porphyrins are more adsorbable over gold substrate and conducting across a molecular junction than phthalocyanines,even though both molecules show a similarity in adsorption and conduction when a terminal thiol linker is attached.A further observation establishes the importance of attractive terms,which includes interaction,orbital and electrostatic energies,in correlating the pEDA study with the transport properties.By progressing this research,further developments could be possible in atomic-scale manufacturing in the future. | Paven Thomas Mathew Fengzhou Fang | 2020 | International Journal of Extreme Manufacturing2020，2，1： | 0 |
