Scanning electron microscopy (SEM) image depicts a baby giraffe formed within a jungle of Ni-Al-C dendrites. As the molten alloy was being solidified inside a graphitic crucible, the melt was decanted, leaving behind a little dendrite wetted by a thin molten blanket. As the jungle got colder, the blanket froze and rejected carbon which eventually crystallized as a graphite cover. Upon further cooling, the graphitic cover wrinkled, due to its thermal expansion coefficient mismatch with metallic substrate, creating a faceted network of creases resembling the familiar skin patches of a giraffe. - Shaahin Amini and Reza Abbaschian, Department of Mechanical Engineering, University of California Riverside
Looking into the dark forest of GaAs/GaInP nanowires imaged by SEM. The nanowires were grown in two steps: first the GaAs stem using a Au particle as seed particle in MOVPE. The sample was removed from the reactor and a layer of HSQ resist was applied by spinning, forming a thin layer of moss. When the GaInP was grown during a second MOVPE step, the resist prevented growth on the substrate and sidewalls of the GaAs stems. The image is artificially colorized, but based on EDS measurements; light green represents GaInP and light brown/red GaAs. The substrate and base of GaAs nanowires has a dark green color to represent the areas where thicker resist was detected. - Daniel Jacobsson, Lund University
A stunning visual pattern of high-performance organic semiconductor crystals obtained using cross-polarized optical microscopy. The image is completely original without editing. The nucleating point shows a pattern that resembles a lone man wearing a curious hat on top of a mountain made from organic crystals amid a sea of other crystals. The cross-polarizer modulates the brightness of the different mountain top, providing a perspective of depth. The Haiku was inspired by the man-like figure: " The scientist sits atop, Mountains of organic crystal snow, Yonder the electrons flow? - Benjamin Tee
Spring is here! False color SEM image of carbon nanotube pillars synthesized by cappilography. – Adrianus I Aria, California Institute of Technology.
