Advantageous rates (soft cap threshold of 120 h / year)

LCM users can benefit from a preferential rate beyond a flexible threshold of 120 h accumulated during the fiscal year. For example, beyond 120 h, the hourly cost applicable to the use of a technique is 5 $/h for internal academic users (chemistry UdeM, QCAM, GCM, RQMP & CGCC) and $ 10 / hr for other academic users.

Training

To have full access  to an LCM system, potential users must attend practical training sessions on the system. The rates are listed below:

  • Personal training (one person): $ 75 academic internal users (chemistry UdeM, QCMA, GCM,  RQMP & CGCC), $ 100 other academics & $ 150 industry
  • Group training (maximum 3 people): $ 50 to $ 100 / additional person

Services and Access Policy

The LCM laboratories are multi-user facilities accessible to the entire scientific community (academic and industrial), given certain user fees. Here is an overview of the services offered by the LCM:

  • Training of researchers to the various spectroscopic and microscopic technics available at the LCM, as well as the sustained supervision during the use of the systems.
  • Professional sample analysis and characterization services; Assistance in the interpretation of the results obtained.
  • Consultation on experimental feasibility : Preliminary exploratory studies to assist some new applicants in assessing the suitability of applying LCM techniques to their specific needs.
  • Assistance in developing methods, developing collaborations and research partnerships.

Booking and usage

At least one hour of use is required to validate a reservation.

The maximum number of hours allowed per person, Monday to Friday, is 9 hours per week, spread over one or more days, from 8 am to 5 pm.

However, there are no limitations on the time of use during evenings and weekends (applicable only to certified trained users on the system and for the SPM and FTIR labs).

Reservations are allowed 2 weeks in advance from the current week.

Laboratories

Scanning Probe Microscopy Laboratory

 

The LCM scanning microscopy unit consists of 7 Atomic Force Microscopes :  Bruker (MultiMode 8, Dimension 3100, Dimension ICON FastScan, Dimension ICON in glove box, E-Scope), ANASYS (NanoIR2), WItec (ALPHA 300RS). These multi-function imaging systems combine performance and complementary applications. They are equipped with accessories and additional modules that enhance their operational capacities and broaden their fields of application: different modes  and techniques of imaging in air, in liquid and variable temperature.

 

These equipment of major interest in the fields of nanosciences and nanotechnologies  allow the direct nanometric scale characterization of the material surfaces.

Consult the LCM regulations and rates.

Technical Characteristics

  • AFM: Atomic force microscopy, in contact Tapping Mode and Peak  Force tapping Mode in air and in liquid.
  • STM: Scanning Tunneling Microscopy, for measuring the topography of conductive and semiconductive surfaces as well as surface distribution of electron density.
  • FMM: Force Modulating Microscopy.
  • LFM: Lateral Force Microscopy, probe the mechanical properties (frictional forces) of the surface.
  • PIM: Phase Imaging Microscopy, detects chemical heterogeneity at the surface and reveals the different phase domains.
  • EFM: Electric Force Microscopy, explores the electrostatic properties at the interface and gives the charge distribution.
  • MFM: Magnetic Force Microscopy, image and elucidates the magnetic properties of the surface.
  • Scan Asyst: Scan Asyst optimization offers a drastic improvement in lateral resolution in AFM imaging thanks to an improved control of the interaction forces between the tip and the surface combined with an automatic adjustment of the optimization parameters, this improves productivity and reproducibility.
  • Peak Force QNM: The PFQNM allows the quantitative mapping of the nano-mechanical properties of surfaces. The nano-mechanical properties such as modulus, adhesion, deformation and dissipation are extracted from each pixel (point-to-sample interaction).
  • Peak Force Tuna : PFTUNA for probing conductivity of fragile samples correlated  to  the quantitative nanomechanical property imaging with PeakForce QNM.
  • KPFM : Kelvin Probe Microscopy, allows the mapping of the surface potential with a nm lateral resolution.
  • High speed (FastScan): Very high-speed (20 Hz) imaging, allowing to follow dynamic phenomena in real time with a nanometric resolution in a non-damaging way for the sample or the probe.
  • Medium: Imaging in air, in liquid medium and at variable temperature.
  • Closed-loop scanner: Returns to a defined point (within nm) for force or nanolythographic spectroscopic measurements.
  • Open geometry and Sample holder (15x15 sq. in.): Suitable for  the coupling  of sophisticated experimental  setup to AFM and for imaging large parts /components without necessary alterations.
  • AFM-Raman: Confocal (2D and 3D) imagery with high spatial resolution (up to 1000 nm) correlated to AFM imaging. Acquisition at a defined point (within a few microns) of Raman spectra.
  • SNOM: Scanning Near-field Optical Microscopy, allowing non-destructive optical imaging with a resolution well beyond the diffraction limit, i.e. a 50-100 nm lateral resolution (possibility to work in air or liquid environment) .
  • AFM-IR: NanoIR2 allows simultaneous acquisition of topographic images with nanometric spatial  resolution coupled to infrared absorption imagery of similar spatial resolution. Acquisition at a defined point (within nm) of infrared spectra over a wide spectral range. Study of the molecular orientation by polarization of the infrared beam.
