Current study results on Machine Learning have been published. According to news originating from Hangzhou, People’s Republic of China, by NewsRx correspondents, research stated, “Strain and defect engineering have profound applications in two-dimensional materials, where it is important to determine the equilibrated atomistic structures with defect conditions under mechanical deformations for computational materials design. Nevertheless, how to efficiently predict relaxed atomistic structures and the associated physical fields on each atom or bond under evolving mechanical deformations remains as an essential challenge.” Financial support for this research came from National Natural Science Foundation of China. Our news journalists obtained a quote from the research from Zhejiang University, “To address this issue, a deep neural network architecture is designed to embed the state of applied strains into the defectengineered atomistic geometry, so that deformation-coupled physical fields of interests on atoms or bonds can be predicted or derived over continuous state of deformations. For demonstration, the combination of applied tensile strains and shear strain on monolayer graphene with random distribution of Stone-Wales defects and vacancy defects is considered. The unique advantage of this framework is the development of strain-embedding concept combined with generative adversarial network, which can be feasibly extended to other material and other conditions. The computational approach sheds light on boosting the efficiency of evaluating physical properties of 2D materials under complex strain and defect states. This work presents a unifying deep learning framework that learns from complex strain states and defected configurations for the prediction of deformation-coupled spatial field values with atomistic resolution. The deep learning method is based on strain embedding and generative adversarial network.”
