Local tools


Clean room facilities

We make use of a broad array of micro- and nano-fabrication tools at open access clean room facilities located at the Ecole Polytechnique and McGill University in Montreal



Nanoscience Group facilities

Our group is a member of the Nanoscience Group at Concordia which shares a large number of facilities

 


Our laboratory

Our laboratory in located in the basement of the Science Pavillion on the Loyola campus. It is a brand new 65 square-meter laboratory space with a low vibration floor, 5 meter high ceiling, sound proofed pump and service room, fume hood, gas (He, N, compressed air) and vacuum service all around the lab, as well as 2 electrical panels with isolated grounds. We have two low-temperature cryostats, a chemical vapor deposition growth chamber, and many other toys.

Instruments located in our lab


Cryogen-free He-3 top-loading VTI cryostat with 9 Tesla magnet

This is a photo of the He-3 cryostat

Low-temperature cryostat (0.3 - 300 Kelvin). Allows a wide range of electron transport experiments in nanosystems as a function of temperature, electric and magnetic field.

 

Variable temperature cryostat (VTI)

This is a photo of the VTI

Low-temperature cryostat (1.5 - 420 Kelvin). Allows a wide range of electron transport experiments in nanosystems as a function of temperature, electric and magnetic field.

 

Mechanical breakjunction cryostat (MBJ)

This is a photo of a low-temperature cryostat

Low-temperature cryostat (4.2 - 300 Kelvin) equipped with a mechanical breakjunction assembly. Allows a wide range of electron transport experiments in nanosystems as a function of mechanical strain.

 

14 Tesla superconducting magnet

This is a photo of the Magnet

14 Tesla magnet and its dewar which can be used with both cryostats (VTI and MBJ).

 

Electrical probe station

This is a photo of the Probe station

Five-probe probe station for sample characterization during microfabrication.

 

Thermal evaporator

This is a photo of the evaporator

Four-source thermal evaporator for thin film depostions.

 

Chemical vapor deposition system (CVD)

This is a photo of the CVD

Gas flowmeters and furnace making up the CVD. The CVD is used for the growth of single-wall carbon nanotubes (SWCNT) and microcrystals of topological insulators (Bi2Se3).

 

Helium leak detector and turbo-pumping station

This is a photo of a helium leak detector

High precision helium-3 and helium-4 leak detector equipped with a turbo-molecular pump. An additional high-volume turbo-pumping station is used for high vacuum pumping. Permits the operation and maintenance of helium-3 and helium-4 low-temperature cryostats.

 

Optical microscope

This is a photo of an optical microscope

High resolution Olympus BX51 optical microscope and XC-50 color digital camera system. Allows easy identification of graphene (carbon monolayer) crystals and characterization of micro-lithography.
