Biasing composite nanostructures

Researchers at the University of Houston and the Singapore University of Technology and Design made a silkworm cocoon-like silicon battery electrode using a non-invasive sacrificial template method and studied their electronic properties with Hummingbird Scientific’s TEM Biasing Manipulator sample holder. The researchers assembled an electrochemical cell with composites of nitrogen-doped carbon (NC) and porous silicon nanorods (NRs) affixed to a 3 mm half Cu grid and Li/Li2O lithium source/electrolyte attached to the mobile probe. The lithiation process is achieved by contacting sample and probe and biasing the probe with a negative bias.

Probe Movement—Step Size Control

This example shows how the probe’s fine movement of Hummingbird’s Scientific biasing manipulator sample holder, can be controlled with high precision in space (X axis in this case) and with different step sizes with just a mouse click. Having different step sizes one click away facilities the probe approach before contacting the sample.
