Environmental Scanning-electron Microscope (eSEM-FEI Quanta 250)
ESEM provides access to studies of wet biological samples, nano-bio composites and nano-fluidic phenomena. Studies of real-time redox chemistry involving nano-objects and the imaging of fluids under microfluidic conditions are some of the topics, in which the ESEM is playing a key role.
What we can offer (with the system):
-
SEM – morphological surface analysis
-
STEM (Scanning Transmission Electron Microscopy) – resolution < 1 nm at 30 kV
-
ESEM – non conducting samples without any coating Imaging of wet samples and liquid water
-
Cryogenic cooling stage
-
Possibility to inject liquid by manipulators while imaging
-
In-situ electrical measurements – 3 probes, probing current 10 nA to 100 mA, probing max. voltage 100 V and probing resistance 7 Ω
-
Extra-large high-resolution surface imaging (up to cm2 areas with nm resolution)
-
EDX – Energy dispersive x-ray spectroscopy
-
In-situ force measurement system
Possibility to fabricate (with the system):
