Hummingbird Scientific’s in-situ Biasing Manipulator is the only reliable TEM holder in the market with proven capability to perform in-situ sample manipulation and site-specific electrical biasing. The holder provides accurate uncoupled movements along the X, Y, and Z axes of motion, allowing for easy point-contact with the sample and high-resolution TEM imaging. The holder is easy to use, requires little maintenance, and is available for all major TEM manufacturers (JEOL, Thermo Fisher Scientific, and Hitachi)

How it Works
Correlate the structure and chemistry of a sample (HRTEM, electron diffraction, EELS, etc.) with its electrical properties.
Manipulate the mobile biasing probe with high spatial resolution to make electrical contacts.
Control—uncoupled—coarse and fine movements along the X, Y, and Z axes. Coarse movements are actuated with thumb-screws. Fine movements are actuated with a piezoelectric controlled with the included controller and graphical user interface.
Take low noise electrical data with individual coax cables.
Use standard 3 mm half grid samples or FIB lift-out grids to prepare your samples.Edit
Characterize Electrical Contacts
Use the full battery of TEM-based characterization techniques to record the structure and chemistry of biased electrical contacts. The wide opening area at the contact between mobile probe and sample is compatible with—and optimal for:
- High-resolution TEM imaging
- High-resolution STEM imaging
- Electron diffraction
- Energy dispersive x-ray spectroscopy (EDS)
- Electron energy loss spectroscopy (EELS)
The example shows a TEM image of a 60 nm-wide contact between the mobile biasing probe and a metal-based sample. The structure of the contact has been resolved with high spatial resolution.Edit
Hummingbird Scientific’s graphical user interface features an intuitive fine movement control panel that facilitates and expedites the probe-sample contact process. Functions for varying the fine motion direction and steep size are available, and any parasitic motion in the axes can be compensated with an integrated compensation algorithm. The user can concentrate on the experiment—not on making the contact. The in-situ TEM biasing manipulator platform comes with and integrated voltage source meter supporting electrical measurements, data plotting, and data recording.Edit
In-situ TEM probing of lithium interfaces for solid-state batteries
Using Hummingbird Scientific’s in-situ TEM Biasing Manipulator holder, researchers at Toyota Research Institute of North America and the University of Pennsylvania devised an experiment in which air-sensitive lithium metal is brought in contact with novel solid-state electrolytes to observe the degradation mechanism during the lithium charge and discharge cycles. They observed dendrites and delamination of lithium metal upon reaction with lithium thiophosphate (LPS) electrolyte. However, when the same electrolyte is doped with lithium iodide, the dopant plays a protective role and prevents such degradation. This improves the lithium cycling capacity. The in-situ TEM manipulation and biasing capabilities can accelerate the fundamental understanding and microstructural evolution of nanostructured battery materials to develop better batteries.

In-situ TEM of microstructural evolution in composite solid-state Li-ion batteries during charge/discharge cycles
Researchers at the University of Central Florida (UCF) have studied the structural integrity of a novel composite electrode composed of a polymer-derived ceramic nanoparticle and edge-functionalized graphene oxide during electrochemical lithiation and delithiation cycles.
They assembled a prototype nanobattery cell with a lithium metal and a SiCNO composite electrode and performed in-situ TEM lithation and delithation for at least two cycles using Hummingbird Scientific’s Biasing Manipulator TEM holder. The observed results demonstrated extraordinary structural stability of the SiCNO nanoparticles with only a 9.36% linear expansion during the lithiation (See Movie on the Left).
