These galleries exhibit images of silicon structures created by methods starting with a single-crystal silicon wafer substrate. Electron and optical imaging techniques, combined with digital image stitching and color enhancement, are used to create the visual representations shown below.

/Intricate shapes formed upon resolidification of a silicon wafer which was first melted by resistive heating. |
/Silicon "micrograss" structures, which form by plasma etching of silicon in an atmosphere which causes small pieces of silicon dioxide to sputter and then block (mask) etching where they land. |
/Geometries formed by etching of silicon in a potassium hydroxide (KOH) solution, which reveals smooth crystalline planes along particular directions. |
