The rapid development of the 3D printing industry has had a positive impact on all walks life. Compared with traditional manufacturing industry, could not only shorten design and cycle, but also great advantages in accuracy. With cloud computing recent years, combination services produced new production model. This paper proposed to use single-screw extrusion printer prepare nanodiamond films. ...

Large-scale molecular dynamics simulation is performed to study the nano-cutting process of single crystal copper realized by single-point diamond cutting tool in this paper. The centro-symmetry parameter is adopted to characterize the subsurface deformed layers and the distribution and evolution of the subsurface defect structures. Three-dimensional visualization and measurement technology are...

Carbon in its various forms, specifically nanocrystalline diamond, may become a key material for the manufacturing of microand nano-electromechanical (M/NEMS) devices in the twenty-first century. To utilize effectively these materials for M/NEMS applications, understanding of their microscopic structure and physical properties (mechanical properties, in particular) become indispensable. The mic...

We investigate the optical properties of polycrystalline diamond membranes containing silicon-vacancy (SiV) color centers in combination with other nano-analytical techniques. analyze correlation between Raman signal, SiV emission, and background luminescence crystalline grains grain boundaries, identifying conditions for addressability single centers. Moreover, we perform a scanning transmissi...

Two types of micron-diamond films were prepared on YG6 substrate by hot filament chemical vapor deposition(HFCVD) method. Morphology and orientation of crystalline growth were evaluated by SEM and XRD. Diamond film coated tools and sapphire wafer’ surface before and after lapping experiment  were contrasted. The results indicated that a significant change in Raman spectrum of two types of micro...

The nitrogen-vacancy (NV) center in diamond has been developed as a promising platform for quantum sensing, especially magnetic field measurements the nano-tesla range with nano-meter resolution. Optical spin readout performance direct effect on signal-to-noise ratio (SNR) of experiments. In this work, we introduce an online optimization method to customize laser waveform readout. Both simulati...
