Imaging Ellipsometer
​
The performance of the thin solid film components of energy storage/conversion and electronic devices depends on their structural uniformity. The effective characterization of these films requires spatially resolved measurements of the layer thickness and optical constants. This metrology tool combines auto-nulling ellipsometry and microscopy suitable for surface characterization with a lateral resolution of up to 1 µm and thickness resolution of ca. 0.1 nm. The ultra-objective, a game changer in the field of ellipsometry, provides an overall focused real-time image. The imaging ellipsometer accommodates liquid/electrochemical cells for monitoring the effects of redox reactions.
Atomic Force Microscopy (AFM) for Air- and Water-Sensitives Materials
Dimension Icon AFM with temperature heater/cooler, Bruker
​
The Dimension Icon AFM is a very effective atomic force microscope. Equipped with the Scan Asyst optimization, this instrument offers a drastic improvement in lateral resolution. With the increased control of the interaction forces between the tip and the surface combined with an automatic optimization of the optimization parameters, this improves productivity as well as reproducibility. Installed in a glove box, this Icon AFM is dedicated to electrochemical AFM imaging of air- and water-sensitive materials. There is also the possibility for heating/cooling capabilities.
This AFM is hosted in the Laboratoire de caractérisation des matériaux (LCM) of Université de Montréal. All inquiries should be addressed to Patricia Moraille.

Atomic Force Microscope for High Resolution Nanoscale Infrared Spectroscopy
(AFM-IR)
NanoIR, Bruker (Anasys Instruments)
​
The NanoIR spectrometer uses an AFM probe to carry out IR measurements on surfaces with ca. 60 nm lateral resolution. It is possible to use this instrument to obtain information (chemical composition, orientation) from samples that are at least 100 nm thick, which is suitable for polymer films and large fibers. To provide signals on a smaller scale like on nanoscale electroactive materials, this NanoIR uses a Quantum Cascade Laser to achieve monolayer sensitivity and obtain IR spectra from samples/domains of about 25 nm in size.
