Nanoscience and nanotechnology facility

Facilities and access

The Leeds EPSRC Nanoscience and Nanotechnology Facility (LENNF) is for the characterisation analysis of soft matter systems such as hybrid organic/inorganic systems. We aim to support external users in soft matter research by providing:

  • Free access at the point of use to a range of state-of-the-art nano-characterisation and nano-fabrication equipment with capabilities to handle soft matter.
  • Assistance with appropriate data analysis methods.
  • Appropriate academic and technical expertise.

We aim to provide external researchers who are eligible for EPSRC funding with free access at the point of use to a wide range of state-of-the-art instrumentation and appropriate academic and technical expertise. Please see the research section for some background and examples of the type of output we can achieve with this equipment.

Facilities

Accessible facilities include a synergistic combination of inter-related techniques for both nano-characterisation and nano-fabrication including:

  • Analytical Cryo-TEM
    • FEI Titan3 Themis 300: X-FEG 300 kV S/TEM with S-TWIN objective lens, monochromator (energy spread approx. 0.25 eV), multiple HAADF/ADF/BF STEM detectors, FEI Super-X 4-detector high solid angle EDX system and Gatan OneView 4K CMOS digital camera.
  • Low kV FEG-SEM
    • Hitachi SU8230: high performance cold field emission (CFE) SEM with 80mm2 Oxford Instruments X-Max SDD detector – Ultra high resolution, low kV, Simultaneous SE, BSE, BF and DF STEM imaging, with nanoscale resolution as well as nanoscale EDX capabilities.
  • Cryo-FIB
    • Dual-beam FEI Helios G4 CX high resolution monochromated Field Emission Gun Scanning Electron Microscope (FEG-SEM) with precise Focused Ion Beam (FIB), a 150mm2 Oxford Instruments X-Max SDD detector, a Quorum cryo-stage and coating/transfer unit and a range of etch and deposition capabilities for Slice & View acquisition of multi signal 3D data sets and in-situ TEM sample preparation.
  • (NAP)-XPS
    • Combined UHV/near ambient pressure (NAP) SPECS EnviroESCA X-ray Photoelectron Spectrometer (XPS) system for surface chemical analysis.
  • Electron beam lithography system and cleanrooms

Access

In order to access the facilities you are required to have, or be eligible to apply for EPSRC funding. Access to the facilities is granted to external users by a steering committee that reviews submitted proposals. To submit a proposal please download and fill out an application form and return via email to Mark S'ari, e: m.s.s'ari@leeds.ac.uk. Within the application form or in an additional document please include the specific equipment request, scientific impact of the research project, detailed description of the research to be conducted and relevant previous or preliminary results.

If you would like to discuss the feasiblity of the proposed work and/or if you have any questions, please contact Mark S’ari, e: m.s.s'ari@leeds.ac.uk

Submitted proposals will be reviewed over a 6 - 8 week period by an internal steering committee. Successful proposals will then be allocated a period of time to carry out the experiment. Instrument access cost and staff time are all covered by the facility for the allocated period.
