Micro-muffins

Cylinders of nickel grown by electroforming and after lift-off of the corresponding resist mask. In some cases, the nickel overpassed the resist (muffins), while other cylinders broke at the base (little tarts). The resist has been written with the photolithography technique.

STEM Viewgraph of a Cross Section

The NWs were placed horizontally on a Si wafer then with the FEI Helios the Pt protection layer was deposited by E-beam and Ion-beam successively. Subsequently a TEM lamellae was prepared in maual mode (bottom left) and then imaged in STEM mode using the same FEI Helios featuring the core GaAs NW with an AlGaAs Shell (dark region in top and bottom right viewgraphs) and a GaAs outer shell. The work has been done by Dr. Jie Tian and Dr. Michael Gao using the ANFF ACT node dual beam FIB Helios.

Ring of Plasmonics

The image shows a special plasmonic structure. On top of a gold layer a larger ellipse was created with electron beam lithography and ion beam etching. Subsequently, an additional gold layer was deposited. In the deeper ellipse structure eight smaller plasmonic ring structures were milled with the FEI Helios 650. The outer ellipse structure should enhance the signal of the smaller plasmonic ring structures.
