Two-photon Lithography System

The team has developed a world-leading two-photon lithography system system with isotopic 80nm feature size, as part of an EPSRC grant (EP/R009147/1). The system utilises a 405nm, diode laser which is focussed down to a diffraction limited spot within the resist.

Class 1000 Cleanroom Booth and Associated Equipment 

Our two-photon lithography system is housed within a class 1000 cleanroom booth that is also home to other fabrication facilities such as spin-coater, hot plates, ultrasonic baths and compressed air. This allows all fabrication to take place within our laboratory.

Bruker Dimension Icon Scanning Probe Microscope

We manage a Bruker Dimension Icon scanning probe microscopy, which is available as part of a shared condensed matter and photonics suite of equipment. The systems is able to carry out a wide range of topographic, electrical and thermal measurements upon the nanoscale. Please contact Sam Ladak, for training and access to booking calendar.

Magneto-optical Kerr Effect Magnetometer (MOKE)

The majority of the magnetometry is carried out by using our home-built MOKE system that can achieve fields of 0.8 Tesla. The system is capable of measuring single magnetic nanostructures  such as magnetic nanowires and artificial spin-ice unit cells (see Fig above). We have also recently used the system to measure our first 3D magnetic nanostructures.

Zeiss Axio Imager Optical Microscope

Also within our laboratory this enables us to do quick and routine inspection of our lithographically written samples. This is used both to inspect patterns before electrodeposition of magnetic material and also to take high resolution images of final samples.

Montana Cryogen-free Cryostat

Our MOKE system is also home to a Montana optical cryostat allowing our magnetometry measurements to be performed between 3.5 to 300K. The system also has electrical connections allowing the measurement of temperature dependent resistivity and magnetotransport. The system is completely cryogen free and achieves base temperature within 4 hours.
