Atomic scale friction studies on single crystal gallium arsenide using atomic force microscope and molecular dynamics simulation

Fan, Pengfei; Goel, Saurav; Luo, Xichun; Upadhyaya, Hari M. (Springer, 2021-07-10)

This paper provides a fresh perspective and new insights on the nanoscale friction investigated using molecular dynamics simulation and atomic force microscope (AFM) nanoscratch experiments. The work considered Gallium ...
An atomistic investigation on the wear of diamond during atomic force microscope tip-based nanomachining of gallium arsenide

Fan, Pengfei; Goel, Saurav; Luo, Xichun; Yan, Yongda; Geng, Yanquan; Wang, Yuzhang (Elsevier, 2020-10-30)

This paper investigated the wear mechanism of diamond during the atomic force microscope (AFM) tip-based nanomachining of Gallium Arsenide (GaAs) using molecular dynamics (MD) simulations. The elastic-plastic deformation ...
Brittle ductile transition during diamond turning of single crystal silicon carbide

Goel, Saurav; Luo, Xichun; Comley, Paul; Reuben, Robert L.; Cox, Andrew (Elsevier Science B.V., Amsterdam., 2013-02-28)

In this experimental study, diamond turning of single crystal 6H-SiC was performed at a cutting speed of 1 m/sec on an ultra precision diamond turning machine (Moore Nanotech 350 UPL) to elucidate the microscopic origin ...
Molecular dynamics simulation of AFM tip-based hot scratching of nanocrystalline GaAs

Fan, Pengfei; Goel, Saurav; Luo, Xichun; Yan, Yongda; Geng, Yanquan; He, Yang; Wang, Yuzhang (Elsevier, 2021-04-08)

GaAs is a hard, brittle material and its cutting at room-temperature is rather difficult, so the work explored whether hot conditions improve its cutting performance or not. Atomic force microscope (AFM) tip-based hot ...
Nanoindentation of polysilicon and single crystal silicon: Molecular dynamics simulation and experimental validation

Goel, Saurav; Faisal, Nadimul Haque; Luo, Xichun; Yan, Jiwang; Agrawal, Anupam (IOP Publishing, 2014-06-06)

This paper presents novel advances in the deformation behaviour of polycrystalline and single crystal silicon using molecular dynamics (MD) simulation and validation of the same via nanoindentation experiments. In order ...
Origins of ductile plasticity in a polycrystalline gallium arsenide during scratching: MD simulation study

Fan, Pengfei; Goel, Saurav; Luo, Xichun; Yan, Yongda; Geng, Yanquan; He, Yang (Elsevier, 2021-03-09)

This paper used molecular dynamics simulation to reveal the origins of the ductile plasticity in polycrystalline gallium arsenide (GaAs) during its nanoscratching. Velocity-controlled nanoscratching tests were performed ...
Surface defects incorporated diamond machining of silicon

Khatri, Neha; Barkachary, Borad; Muneeswaran, B.; Al-Sayegh, Rajab; Luo, Xichun; Saurav, Goel (IOP, 2020-07-31)

This paper reports the performance enhancement benefits in diamond turning of the silicon wafer by incorporation of the Surface Defect Machining (SDM) method. The hybrid micromachining methods usually require additional ...
