Deep learning-based molecular dynamics simulation reconfiguration of efficient heat energy transport of Gra/h-BN heterointerface
We investigate the reconfiguration scheme of efficient heat energy transport of the Gra/h-BN heterointerface by a hybrid enhanced machine learning method combining an integrated iterative method, automatic modeling, non-equilibrium molecular dynamics calculation, and convolutional neural network (CNN). The results show that the method identifies the optimal defect distribution in gra/h-BN from tens of millions of possible defect configurations, and the interfacial thermal conductivity (ITC) of the vdW gra/h-BN heterointerface in the optimal defect distribution is 97% higher than that in the original gra. Furthermore, the heat transfer transformation of the vdW gra/h-BN heterointerface with different defect distributions at room temperature can be observed efficiently. The dependency law between the defect distribution and the ITC is revealed by combining the CNN model of the ResNet network. The efficient heat energy transport design can promote the sustainable service life of materials and structures.
期刊介绍:
Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology.
In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics.
APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field.
Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
