Tools: FEI Tecnai Osiris (S)TEM
Here, the highly porous, super-lattice type, periodic arrangements of nano-plasmonic, right-handed Silicon (Si)-Silver(Ag) chiral heterostructure metamaterial platform were fabricated by means of subsequent and repeated electron-beam glancing angle deposition from Si and Ag sources. The figure collage shows the scanning transmission electron microscopy (STEM) image which enabled a prominent ability to create contrast and distinguish Si and Ag sub-helical segments (left image), the high-angle-annular-dark-field STEM enabled to focus on isolated single helicaL heterostructure system (right top image) and the atomic resolution energy-dispersive X-ray spectroscopy-based material mapping enables to map the material along single Si-Ag helical heterostruture metamaterial (right bottom image).

This stunning blue ocean with vortex and wave is from the self-assembly of block copolymers in the nanoscale. From this image, we can find various amazing structures in the nanoworld, which are just dominated by several simple interactions. Science is like this blue ocean, rich, fascinating, and mysterious, riveting all of us to its beauty.
SnSe HAADF-STEM Image

NNCI Site: Center for Nanoscale Systems, Harvard University
Tool: TEM-11 JEOL ARM
This high resolution high annular dark field scanning transmission electron microscope (HAADF-STEM) image is of the ferroelectric material SnSe. Alternating bright and dark atoms can be seen, which correspond to Sn and Se respectively, allowing for the direct observation of the crystallographic structure of this novel material. This image was acquired by aligning and summing several raw images, thereby reducing scan noise.

This image depicts a titled SEM view of vapor-liquid-sold (VLS) growth of silicon under a waveguide ring resonator area before processing it with the chemical mechanical polishing (CMP) machine. The growth method over a large surface area creates a “moon crater” like surface due to the anisotropic catalyzed silicon whisker growth.

We are developing highly reflective, lightweight films for laser-powered interstellar travel. One of our prototypes became corroded during one of the fabrication steps and looked like this in the optical microscope. More specifically, we grew a thin metalized film on top of a ceramic film that coated a double-side-polished silicon chip. The backside of the chip was corroded during the growth process of the metalized film. We deposited another thin ceramic film over the thin metalized film.

This was a negative stain that went wrong (but “oh so right”). We're guessing that there was something in the buffer that made the uranyl acetate precipitate into these amazing shapes. The specimen itself was unusable for scientific purposes but the images themselves were quite striking.

NNCI Site: SENIC
Tool: Zeiss Auriga FIB/FESEM
Metallic copper droplets were deposited on carbon fiber tow through electroplating to create this pattern. Polymer coating on the surface of the carbon fiber prevents the fiber from being wetted by copper which creates bead like droplets depicted in the image.
